[0001] This utility model relates to the technical field of sodium dihydrogen phosphate production equipment, specifically to a sowing and soil covering device based on grassland vegetation planting. Background Technology

[0002] Soil covering refers to the process of covering the seeds with soil after sowing. Covering the seeds with a certain thickness of soil protects them, regulates temperature and humidity, promotes germination, and provides a suitable growing environment for the seedlings. In grassland greening, after the seeds are sown in the furrows, soil covering devices are used to cover the furrows to improve the germination rate of the seeds.

[0003] Most existing soil covering devices for grassland planting rely on soil covering wheels to push soil from both sides of the furrow into the furrow, thus covering the seeds. However, during operation, when the soil moisture is high, soil tends to stick to the surface of the soil covering wheel, resulting in uneven soil covering and affecting the quality of seed coverage. Workers need to manually clean it with shovels or other tools. Due to the high viscosity of the soil, cleaning it after it sticks to the surface of the soil covering wheel is quite laborious, and the soil-covering side of the wheel needs to be cleaned frequently. This undoubtedly reduces work efficiency and causes many inconveniences to the normal use of soil covering devices for grassland planting. Utility Model Content

Detailed Implementation

[0020] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0021] like Figure 1-3 As shown in the figure, this embodiment proposes a sowing and soil covering device based on grassland greening planting, including a frame component 1, a soil covering component 3 and a cleaning component 4.

[0022] In this embodiment, a soil covering component 3 is provided on the frame assembly 1, and a cleaning component 4 is provided on the soil covering component 3. The frame assembly 1 is the basic support component of the device, used to support the film covering component 2, the soil covering component 3 and the cleaning component 4, and to realize the adjustment and traction connection of the overall size of the device. The film covering component 2 is used to cover the soil before the soil covering operation, further reducing soil moisture evaporation, maintaining soil temperature and providing a suitable environment for seed germination. The soil covering component 3 is the core component for completing the soil covering operation, used to cover the seed surface with the soil after sowing, ensuring that the seeds are in close contact with the soil and providing water and nutrients for seed germination. The cleaning component 4 is used to clean the soil adhering to the soil covering surface of the soil covering wheel 306.

[0023] The soil covering component 3 includes two sets of soil covering wheels 306 for covering the seeds. The soil covering wheels 306 are arranged in two sets, symmetrically and obliquely. When the device moves, the soil covering wheels 306 come into contact with the ground. The two sets of obliquely symmetrical soil covering wheels 306 gather the soil towards the center and cover the seed surface, achieving uniform soil covering. The soil covering wheels 306 can be made of rubber, which can reduce the crushing damage to the original vegetation on the grassland surface and meet the requirements of grassland ecological protection.

[0024] In this embodiment, the cleaning component 4 includes a scraper 401, a rotating shaft 402, a gear 403, and a rack 408.

[0025] The scraper 401 is rotatably mounted on the covering wheel 306 and is in contact with the soil covering surface of the covering wheel 306. In this embodiment, the scraper 401 is preferably made of stainless steel to ensure good wear resistance and corrosion resistance, adapting to the erosive environment of grassland soil. The design of being in contact with the surface of the covering wheel 306 can ensure that the soil adhering to the surface of the covering wheel 306 is completely scraped off, which is convenient and quick.

[0026] Furthermore, the scraper 401 is connected to the gear 403 via the rotating shaft 402, and the scraper 401, rotating shaft 402, and gear 403 can rotate synchronously. The rack 408 is located on one side of the gear 403 and is used to drive the gear 403 to rotate. The rotating shaft 402, as a power transmission component, can transmit the rotational power of the gear 403 to the scraper 401, thereby enabling the scraper 401 to rotate. The gear 403 and the rack 408 mesh to form a gear and rack transmission mechanism, ensuring the stability of the rotation of the rotating shaft 402 and preventing the scraper from shaking and affecting the cleaning effect. Through the gear and rack transmission mechanism, the linear motion of the rack 408 can be converted into the rotational motion of the gear 403, thereby driving the scraper 401 to rotate, so as to achieve rapid cleaning of the soil-covering wheel 306 by the scraper 401.

[0027] In this embodiment, specifically, the frame assembly 1 includes a split beam 101, a threaded column 102, and a hexagonal base 103. The frame assembly 1 is made of high-strength aluminum alloy, which has the characteristics of lightweight and high rigidity, reducing the overall weight of the device and facilitating transportation.

[0028] The split beam 101 consists of two sets, interconnected by threaded columns 102. The split beam 101 provides the mounting base for components such as the crossbeam 104 and the second lifting shaft 301. The two sets of split beams 101 allow the frame structure to be disassembled, facilitating transportation and on-site assembly, while also providing a basis for adjusting the frame width.

[0029] Furthermore, one end of the threaded column 102 is rotatably connected to a group of separate beams 101, and the other end of the threaded column 102 is threadedly connected to another group of separate beams 101. When adjusting the width of the frame, rotating the threaded column 102 can change the distance between the two groups of separate beams 101, thereby adapting to the soil covering of different widths of sowing areas or different specifications of mulch, and improving the versatility of the device.

[0030] Furthermore, one end of the threaded column 102 is provided with a hexagonal seat 103, which has a regular hexagonal structure and can be adapted to common tools such as wrenches, making it easy for operators to rotate the threaded column 102 to adjust the width of the frame, reducing the difficulty of operation and improving the adjustment efficiency.

[0031] In this embodiment, specifically, a crossbeam 104 is provided on the side of the split beam 101 near the soil covering wheel 306. This crossbeam serves two purposes: firstly, to mount the traction frame 105, and secondly, to provide a mounting carrier for the first lifting shaft 201 of the mulching assembly 2. This ensures a reasonable spatial layout between the mulching assembly and the soil covering assembly, guaranteeing a smooth workflow. Traction frames 105 are rotatably mounted on the top of the split beam 101 and the ends of the crossbeams 104. The ends of the traction frames 105 are connected by bolts, forming a movable connection. The entire structure constitutes a triangular traction structure. This structure can stably transmit traction power, such as the power of a tractor or other traction equipment, to the device. Simultaneously, the rotatable connection design allows the device to adaptively adjust the traction angle in uneven grassland terrain, preventing tilting or damage caused by uneven force during traction and improving the device's terrain adaptability.

[0032] In this embodiment, specifically, a covering component 2 is provided at the bottom of the crossbeam 104, which is used to cover the soil with a film.

[0033] Furthermore, the coating assembly 2 includes a first lifting shaft 201, a first pin hole 202, a socket 203, and a film rod 204.

[0034] The first lifting shaft 201 is located at the bottom of the crossbeam 104. The first lifting shaft 201 adopts a telescopic rod structure and is vertically fixed at the bottom of the crossbeam 104 to provide support for the socket 203 and the film rod 204. By adjusting its length, the distance between the film roll on the film rod 204 and the ground can be changed to adapt to the film covering requirements of different thicknesses of soil covering layers or different terrains.

[0035] Furthermore, a first pin hole 202 is formed on the first lifting shaft 201 for adjusting the length of the first lifting shaft 201. A bolt matching the first pin hole 202 is provided on the first lifting shaft 201. The first pin holes 202 are evenly spaced along the length of the first lifting shaft 201 and cooperate with the matching bolts. When the first lifting shaft is adjusted to the appropriate length, the bolt is inserted into the corresponding first pin hole 202 to fix the length of the first lifting shaft, preventing the shaft from extending or retracting due to vibration during the coating process, ensuring stable coating height, and improving coating quality.

[0036] Furthermore, the socket 203 is located at the bottom end of the first lifting shaft 201 and is used to support the film rod 204. The film rod 204 is slidably disposed inside the socket 203 and is used to pass through the film roll. The sliding engagement between the film rod 204 and the socket 203 facilitates the quick installation and disassembly of the film rod and improves the efficiency of film roll replacement.

[0037] In this embodiment, the soil covering component 3 specifically includes a second lifting shaft 301 and a second pin hole 302.

[0038] The second lifting shaft 301 is located at the bottom of the split beam 101. The second lifting shaft 301 provides support for the reversing seat 303, the horizontal shaft 305 and the covering wheel 306. By adjusting its length, the contact pressure and soil penetration depth of the covering wheel 306 with the ground can be changed to adapt to the looseness of different grassland soils. For example, the soil penetration depth requirements of sandy soil and clay soil are different, ensuring that the soil covering thickness is uniform.

[0039] Furthermore, a second pin hole 302 is provided on the second lifting shaft 301 for adjusting the length of the second lifting shaft 301. A bolt matching the second pin hole 302 is provided on the second lifting shaft 301. The bolt and the second pin hole 302 cooperate to fix the adjusted length of the second lifting shaft 301, preventing the expansion and contraction of the lifting shaft during the backfilling process from causing fluctuations in the backfilling depth and ensuring stable backfilling quality.

[0040] In this embodiment, the soil covering component 3 specifically includes a reversing seat 303, a positioning screw 304, and a horizontal axis 305.

[0041] The reversing seat 303 is rotatably mounted at the bottom end of the second lifting shaft 301 and is used to connect the horizontal shaft 305. A positioning screw 304 for positioning the horizontal shaft 305 is movably mounted on the reversing seat 303. The horizontal shaft 305 is located at the bottom of the reversing seat 303 and is used to connect the covering wheel 306. The rotating shaft 402 is rotatably mounted inside the horizontal shaft 305. Removing the positioning screw 304 can adjust the tilt angle of the covering wheel 306 to meet different covering requirements and ensure that the covering wheel 306 always maintains good contact with the soil. This avoids the problem of some areas not being covered or being covered too thickly due to terrain undulations. When the covering wheel 306 is adjusted to a suitable angle, tightening the positioning screw 304 can fix the position of the horizontal shaft 305 through friction, preventing the reversing seat from rotating arbitrarily and causing the covering angle to shift, thus improving the stability of the device operation.

[0042] In this embodiment, specifically, the cleaning component 4 also includes a protective cover 404, which is disposed on one side of the horizontal shaft 305 to protect the gear 403. The protective cover 404 can prevent weeds, stones, and other debris from getting caught in the meshing point between the gear 403 and the rack 408 during grassland operations, thus avoiding jamming and damage to the transmission mechanism. The groove at the bottom of the protective cover 404 that matches the rack 408 ensures smooth movement of the rack 408.

[0043] Specifically, the top of the protective cover 404 is provided with a first sleeve 405 and a second sleeve 406 for protecting the rack 408. The second sleeve 406 is slidably disposed on top of the first sleeve 405, and the top wall of the second sleeve 406 is connected to the top of the rack 408, which can drive the rack 408 to slide up and down synchronously. The first sleeve 405 is disposed on top of the protective cover 404 to house the second sleeve 406. The first sleeve 405 provides guidance for the sliding of the second sleeve 406, ensuring the stability of the linear movement of the rack 408 and preventing rack misalignment that could lead to gear meshing failure. The cooperation between the second sleeve 406 and the first sleeve 405 forms a telescopic structure, which on the one hand protects the rack 408 from interference from external debris, and on the other hand extends the rack's stroke, increasing the adjustment range of the scraper 401.

[0044] In this embodiment, a foot pedal 407 is provided at the top of the second sleeve 406, which makes it easy for the operator to drive the second sleeve 406 down by stepping on it, thereby driving the rack 408 to move, reducing the intensity of operation and improving the ease of operation of the cleaning component.

[0045] In this embodiment, a return spring 409 is fitted inside the first sleeve 405 to provide elastic support for the second sleeve 406. When the operator presses the foot pedal 407 to lower the second sleeve 406, the return spring 409 is compressed and stores elastic potential energy. When the operator releases the foot pedal 407, the return spring 409 releases the elastic potential energy, pushing the second sleeve 406 to rise and reset, thereby driving the rack 408 and gear 403 to reset, so that the scraper 401 returns to the initial position of being in contact with the soil covering wheel 306, realizing the automatic reset of the cleaning components and improving operating efficiency.

[0046] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0047] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
