Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural machinery, in particular to a spinach sowing and fertilizing machine. Background Art
[0002] In modern mechanized agricultural planting, the seed drill is a key piece of equipment for efficient and precise seeding. Traditional seed drills typically consist of a furrowing mechanism, a sowing mechanism, a fertilizing mechanism, and an irrigation mechanism, which work together to complete a series of operations, from furrowing to sowing, fertilizing, and irrigation. However, existing seed drills directly perform the furrowing operation without pre-treating or leveling the soil. This direct furrowing method can easily lead to inconsistent furrowing depth when used on uneven or loose soil, affecting sowing quality. Furthermore, under varying soil conditions, such as dry, wet, loose, or heavy soil, direct furrowing can cause soil collapse, uneven furrowing, or inconsistent furrowing depth, which in turn affects seeding depth and germination rate. More importantly, direct furrowing on uneven soil can require frequent adjustments to the furrowing plow, increasing operating time and labor intensity, and reducing operational efficiency.

[0023] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.
[0024] It should be noted in advance that, in this utility model, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connected," and "fixed" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances. Furthermore, in this utility model, unless otherwise expressly specified or limited, a first feature "above" or "below" a second feature may include direct contact between the first and second features, or may include contact between the first and second features not being in direct contact but through another feature between them.
[0025] like Figure 1 As shown, a spinach sowing and fertilizing machine includes a frame 1, the frame 1 is provided with a walking mechanism, a ditching mechanism, a fertilizing mechanism, a sowing mechanism, a covering mechanism and an irrigation mechanism, a leveling mechanism is provided at the front end of the frame 1, the leveling mechanism includes a bracket 2 hinged to the frame 1, and a soil leveling wheel 3 installed on the bracket 2, an electric telescopic cylinder 4 is connected between the bracket 2 and the frame 1, and the electric telescopic cylinder 4 can push the bracket 2 to swing to adjust the height of the soil leveling wheel 3.
[0026] In the above structure, the running mechanism can be selected from existing conventional structures, such as four running wheels driven by a drive motor. A gantry 5 is installed at the front end of the frame 2, and a rotating shaft 6 is rotatably installed at the bottom of the gantry 5. The rear end of the bracket 2 is rotatably connected to the rotating shaft 6.
[0027] A synchronization block 7 is coaxially fixedly installed on the rotating shaft 6. The synchronization block 7 is connected to the soil leveling wheel 3 through a chain drive so as to rotate synchronously with the soil leveling wheel 3. A driven sprocket 8 is also provided on the frame 1, which is connected to the synchronization block 7 through a chain drive. The driven sprocket 8 is connected to the sowing mechanism for providing power to the sowing mechanism.
[0028] like Figure 2 As shown, the sowing mechanism in this embodiment includes a base 9 mounted on a vehicle frame 1, a drive shaft 10 passing through the base 9, and a seed box 11 disposed on the base 9. A seed screening ring 14 is disposed in the seed box 11. A driven sprocket 8 is fixedly mounted on one end of the drive shaft 10. The other end of the drive shaft 10 is connected to the seed screening ring 14 through a gear train to drive the seed screening ring 14 to rotate. The outer peripheral surface of the seed screening ring 14 is evenly spaced with a plurality of seed drop grooves 12. The bottom of the seed box 11 is connected to a sowing tube extending downward. The top of the seed box 11 is provided with a feed port and a removable cover. The structure of the sowing mechanism is relatively simple, mainly consisting of a base 9, a drive shaft 10, a seed box 11, and a seed screening ring 14. The rotation of the seed screening ring 14 is achieved through the transmission of the gear train. This structural design is easy to manufacture and maintain, has high reliability, and reduces production costs and maintenance difficulties.
[0029] When the soil-leveling wheel 3 is in operation, it contacts and rubs against the soil surface, causing it to rotate. This in turn drives the synchronization block 7, which in turn drives the driven sprocket 8. This power is then transmitted to the seed screen ring 14 via the rotating shaft 6 and the gear train. The rotation of the seed screen 11 drives the seeds in the seed drop groove 12 to be intermittently discharged from the seeding tube, thereby achieving seeding. By utilizing the friction between the soil-leveling wheel 3 and the soil as a power source, no additional power device is required to drive the seeding mechanism, saving energy and improving the machine's energy efficiency. This power transmission method also simplifies the transmission system, reducing the machine's complexity and manufacturing cost. It is worth noting that the soil-leveling wheel 3, which contacts and rubs against the soil during operation, can automatically adjust its rotation speed according to the actual soil conditions, thereby driving the rotation speed of the seed screen ring 14 to change accordingly, achieving adaptive seeding. In cases of hard or loose soil, the rotation speed of the soil-leveling wheel 3 changes accordingly, ensuring consistent seeding spacing and improving the adaptability and reliability of seeding. Those skilled in the art should know that in the initial stage of the machine's operation, the seeds will not fall directly and will fall on the soil that has not been leveled and furrowed. This is because the seeds on the seed screening ring 14 need to be driven by the seed screening ring 14 to rotate half a circle before they fall. At this time, the machine has moved forward a certain distance, and the seed drop tube can already be above the soil after the furrow is dug.
[0030] The soil covering mechanism in this embodiment includes two soil-filling plates 15 positioned at the rear end of the seeding tube. These plates 15 are arranged obliquely and symmetrically to push soil from both sides of the trench into the trench, thereby covering the seeds. The simple design of the soil-filling plates 15 makes them easy to manufacture and install, reducing production costs and maintenance.
[0031] The irrigation mechanism also includes a water tank 13 located behind the soil covering mechanism. The bottom of the water tank 13 is connected to a water outlet pipe via a water pump, and a nozzle is provided at one end of the outlet pipe. The water pump pumps water from the water tank 13 to the outlet pipe, where it is sprayed onto the soil through the nozzle, ensuring that the soil is well moistened after sowing, which is beneficial for the seeds to absorb water and germinate.
[0032] like Figure 3 As shown, the furrowing mechanism includes a furrowing plow 16 disposed behind the leveling mechanism and a lifting mechanism for driving the furrowing plow 16 up and down. The lifting mechanism includes a screw-nut pair and a lifting motor that drives the screw-nut pair. The nut structure of the screw-nut pair is connected to a support bracket 17, and the furrowing plow 16 is fixedly mounted on the support bracket 17. The depth of the furrowing plow can be adjusted according to the planting requirements of the crop to ensure that the sowing furrow meets the growth requirements of the seed.
[0033] In addition, a fertilizing mechanism is provided between the furrowing mechanism and the sowing mechanism. The fertilizing mechanism can promptly carry out fertilization after furrowing and before sowing, achieving simultaneous sowing and fertilizing, ensuring that the seeds can immediately obtain nutrients after sowing, promoting rapid seed growth, and improving crop yield and quality. The fertilizing mechanism can be implemented using an existing conventional mechanism. The invention of this application does not lie in the specific structure of the fertilizing mechanism, and therefore will not be described in detail.
[0034] The workflow of the spinach sowing and fertilizing machine provided in the above embodiment is roughly as follows:
[0035] First, the operator places spinach seeds into the seed box 11 and ensures the feed port cover is properly installed to prevent the seeds from spilling during operation. Adjust the furrowing plow depth based on soil conditions and sowing requirements to create an appropriate sowing furrow. Check the irrigation system's water tank 13 to ensure sufficient water, start the water pump, and place the water outlet pipe and nozzle in standby mode. Start the fertilization mechanism (if simultaneous fertilization is required) and set the desired fertilizer dosage. Adjust the electric telescopic cylinder 4 to ensure the soil leveling wheel 3 is at an appropriate initial height to level the soil before trenching.
[0036] The machine begins to move forward, with the traveling mechanism driving the frame 1. The soil-leveling wheel 3 first contacts the ground soil, initially leveling and compacting the soil surface to ensure a uniform and dense surface. As the soil-leveling wheel 3 rolls, it drives the synchronous block 7 via a chain drive, which in turn drives the driven sprocket 8, providing power to the sowing mechanism. After the soil-leveling wheel 3 pre-treats the soil, a furrowing plow 16 opens the soil behind the leveling mechanism, creating a sowing furrow of appropriate depth and width. After furrowing, the fertilizing mechanism evenly applies fertilizer to the sowing furrow before sowing to provide nutrients for the seeds. The sowing mechanism's driven sprocket 8 receives power from the soil-leveling wheel 3 via a chain drive, which in turn rotates the drive shaft 10, transmitting the power to the seed screening ring 14 via a gear train. The rotation of the seed screening ring 14 causes the seeds in the seed drop trough 12 to be intermittently discharged from the sowing tube. The seeds then fall along the sowing tube into the sowing furrow created by the furrowing plow 16, achieving evenly spaced sowing.
[0037] After the seeds fall into the sowing furrow, two obliquely symmetrically arranged soil-filling plates 15 push the soil on both sides of the furrow into the furrow to close it, covering the seeds and achieving uniform soil covering. The design of the soil-filling plates 15 ensures that the soil can be smoothly closed to cover the seeds, reducing the risk of soil collapse and seed exposure. After covering the soil, the water pump of the irrigation mechanism transports the water in the water tank 13 to the outlet pipe and sprays it onto the soil through the nozzle, ensuring that the soil has good moisture after sowing, which is conducive to the absorption of water and germination of the seeds. The flow rate of the water pump and the spraying range of the nozzle can be adjusted according to the moisture of the soil and the needs of the crops to achieve precise irrigation and improve the utilization efficiency of water resources.
[0038] The spinach sowing and fertilizing machine of the present invention pre-treats and levels the soil by arranging a height-adjustable soil-leveling wheel at the front end of the frame and adjusting the height of the leveling wheel using an electric telescopic cylinder, thereby ensuring that the soil surface is uniform and dense. The soil-leveling wheel is connected to the synchronous block through a chain drive, which drives the driven sprocket to rotate, providing power to the sowing mechanism and achieving equidistant sowing of seeds. The furrowing plow accurately digs furrows on the leveled soil, the fertilizing mechanism applies fertilizer after the furrowing, the sowing mechanism sows the seeds into the furrows, the soil-closing plate closes the soil to cover the seeds, and finally the irrigation mechanism sprays water to ensure that the soil is moist. This design not only improves the sowing quality, but also reduces labor intensity and production costs, and has significant economic benefits and broad application prospects.
[0039] In order to make it easier for ordinary technicians in this field to understand the improvements of the present invention over the prior art, some drawings and descriptions of the present invention have been simplified, and the above-mentioned embodiments are better implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
