Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a sowing device used for mulch film operations. Background Art

[0002] Mulching is a common technique in agriculture, which improves crop yield and quality by covering the ground with mulch. Mulch is usually made of plastic material and covers between crop rows or the entire ground. It has the functions of heat preservation, moisture retention, weed prevention and pest reduction. When implementing mulching, it is necessary to make appropriate planting holes on the mulch according to the planting distance and planting position of the crop, and then sow or plant.

[0003] Existing wheel seeders use blades or needle-like structures to puncture the ground film, thereby forming planting holes on the ground film. In order to better utilize the advantages of the ground film, planters usually use thickened polyethylene film or polypropylene film to cover the planting plots. The thickness of the thickened ground film is usually above 0.02mm. As a result, during actual use of the above-mentioned wheel seeder, it is easy for it to be difficult to puncture the thickened ground film, and after the ground film is punctured, the planting holes are prone to shrinkage and displacement, resulting in the displacement of seeds during sowing, thereby affecting the sowing effect.

[0004] After searching, Chinese patent document CN116889168A discloses an electric heating film-breaking device for a hole-seeker. The hole-seeker uses a tractor battery power supply to pierce the ground film with a hole-forming device, and then heats the outer circle of the hole-forming device with electricity through an electric heating wire to simultaneously melt the ground film at high temperature, thereby stably forming a hole in the ground film corresponding to the sowing hole.

[0005] However, in actual use, the above-mentioned electrothermal film-breaking device still has difficulty in forming suitable planting holes on the thickened ground film. For example, the thickened ground film is very easy to stick to the outer ring of the hole-forming device. As the hole-forming device moves and rotates, the thickened ground film is torn or even torn, which greatly affects the sowing efficiency. In addition, when breaking holes, due to the electric heating effect, the planting holes on the thickened ground film are prone to shrinkage, and the seeding device is prone to skewed seedlings when sowing, which affects the sowing effect. Summary of the invention

[0006] The purpose of the utility model is to provide a sowing device in the process of implementing mulch film operations, so as to improve the success rate of drilling holes in mulch films, improve the quality of drilling holes, avoid the occurrence of seed deviation, and thus improve the sowing efficiency.

[0007] In order to achieve the above purpose, the utility model adopts the following scheme:

[0008] A sowing device for mulching operation, comprising a sowing box for storing seeds, a seed separation rack, a wheel disc and a hole opening assembly;

[0009] The sowing box is installed on one side of the seed separation rack, the sowing box is connected to the seed separation rack through a conveying channel, the wheel is installed on the outside of the seed separation rack, and a sowing outlet is provided on the side wall of the wheel;

[0010] The hole opening assembly is arranged on the side wall of the wheel disc, and the hole opening assembly is arranged in a ring shape along the axis of the wheel disc. The hole opening assembly includes an outer cone shell and an inner cone shell. The outer cone shell is installed on the side wall of the wheel disc, and a cavity for accommodating the inner cone shell is provided inside the outer cone shell. The inner cone shell is embedded in the cavity, and the inner cone shell is connected to the sowing outlet. A flip cover is provided at the opening of the inner cone shell.

[0011] Preferably, the flip cover is hinged to the outer cone shell through a rotating shaft. With this arrangement, the flip cover has the freedom to rotate around the rotating shaft, which facilitates the flip cover to rotate relative to the rotating shaft to close or open the opening of the inner cone shell, and further facilitates the flip cover to lock the opening of the inner cone shell after the outer cone shell performs a hole-making operation on the ground film, thereby smoothly completing the sowing operation.

[0012] Preferably, an elastic member for providing restoring force to the flip cover is provided between the flip cover and the side wall of the wheel disc. In this way, the elastic member is used to provide elastic force to the flip cover, so that the flip cover fits the opening of the inner cone shell in a non-sowing state, ensuring that the opening of the inner cone shell is closed, avoiding the seeds from scattering, and further improving the sowing effect.

[0013] Preferably, the flip cover plate is an L-shaped plate, one end of the L-shaped plate closes the opening of the inner cone shell, and the other end of the L-shaped plate is connected to the side wall of the wheel disc through an elastic member.

[0014] Preferably, a rib plate is provided at the bend of the L-shaped plate. In this way, the rib plate is used to enhance the structural strength of the bend of the L-shaped plate, further improving the impact resistance of the flip cover, and is conducive to preventing the L-shaped plate from deforming under the pressure of the ground.

[0015] Preferably, the elastic member is a compression spring, one end of the compression spring is connected to the flip cover plate, and the other end of the compression spring is connected to the side wall of the wheel disc.

[0016] Preferably, a wedge block is arranged on the back side of the outer cone shell. In this way, the wedge block is used to further improve the hole opening effect of the outer cone shell, which is conducive to forming an oblong hole on the ground film.

[0017] Preferably, a mounting frame for connecting a walking device is provided on one side of the seed separation frame, so that the sowing device can be adapted to walking devices of different specifications, further improving the adaptability.

[0018] Compared with the prior art, the sowing device for ground film operation provided by the utility model has the following substantial features and progress: the sowing device for ground film operation provides a hole-opening component arranged in a ring shape on the side wall of the wheel disc, uses the outer cone shell in the hole-opening component to perform hole-opening operation on the ground film, and combines with the inner cone shell to perform seed sowing operation, thereby improving the success rate of hole-opening on the thickened ground film; when the outer cone shell presses down the thickened ground film and pierces the thickened ground film, the flip cover plate flips relative to the outer cone shell, thereby punching the thickened ground film The opening of the hole forms a propping effect, which further improves the opening quality and solves the problem of incomplete hole opening for thickened mulch film, thereby improving the sowing efficiency. In addition, the outer cone shell is equivalent to the extension structure of the inner cone shell to the outside. The outer cone shell and the inner cone shell form a "mouth in a mouth" structure. When the outer cone shell is used to open holes for the mulch film, it has the advantage of expanding the hole opening, which is beneficial to alleviate the problem of hole opening shrinkage after the thickened mulch film is punctured. At the same time, when the inner cone shell is used to implement sowing operations, it guides the seeds, realizes precise sowing, and avoids the occurrence of seedling deviation.

DETAILED DESCRIPTION

[0023] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-Figure 3 As shown, in the embodiment of the utility model, a sowing device for ground film operation is proposed, which aims to improve the success rate of opening holes in the ground film and the quality of the holes during the ground film operation, thereby improving the sowing efficiency.

[0025] In order to better utilize the advantages of mulching, thickened mulch is usually used to cover the field in the prior art. The thickness of the thickened mulch is usually above 0.02 mm. As a result, the existing sowing device is prone to having difficulty piercing the thickened mulch, which in turn affects the sowing effect.

[0026] In view of the above problems, a sowing device for ground film operation is proposed in the embodiment of the utility model. The sowing device is provided with a hole-opening assembly 4 arranged in a ring shape on the side wall of the wheel 3, and uses the outer cone shell 41 in the hole-opening assembly 4 to perform hole-opening operation on the ground film, thereby improving the success rate of opening holes in the thickened ground film. In the process of the outer cone shell 41 pressing down the thickened ground film and piercing the thickened ground film, the flip cover plate 43 is flipped relative to the outer cone shell 41, thereby forming a propping effect on the opening on the thickened ground film, further improving the opening quality, solving the problem of incomplete hole opening in the thickened ground film, and thus improving the sowing efficiency.

[0027] like Figure 1 As shown, a sowing device for mulching operation includes a sowing box 1 for storing seeds, a seed separation rack 2, a wheel 3 and a hole opening assembly 4. Figure 2 As shown, the sowing box 1 is installed on one side of the sowing rack 2. The sowing box 1 is connected to the sowing rack 2 through a conveying channel 5. The wheel disc 3 is installed on the outer side of the sowing rack 2. A sowing outlet 6 is provided on the side wall of the wheel disc 3.

[0028] like Figure 1 Combination Figure 3 As shown, the opening assembly 4 is arranged on the side wall of the wheel disc 3. The opening assembly 4 is arranged in a ring shape along the axis of the wheel disc 3. Figure 3 As shown, the opening assembly 4 includes an outer cone shell 41 and an inner cone shell 42. The outer cone shell 41 is mounted on the side wall of the wheel disc 3. A cavity for accommodating the inner cone shell 42 is provided inside the outer cone shell 41. The inner cone shell 42 is embedded in the cavity. The inner cone shell 42 is connected to the sowing outlet 6. A flip cover plate 43 is provided at the opening 45 of the inner cone shell 42.

[0029] The outer cone shell 41 is used to perform hole-making operations on the ground film, and the tip formed by the side wall is used to pierce the thickened ground film to form an opening. The inner cone shell 42 is used to guide the seeds, so that the seeds can smoothly enter the opening formed by the outer cone shell 41 piercing the thickened ground film. When the ground squeezes the flip cover 43, the flip cover 43 opens the opening 45 of the inner cone shell 42, which, on the one hand, further guides the seeds and realizes precise sowing; on the other hand, the flip cover 43 and the outer cone shell 41 simultaneously support the opening on the thickened ground film, expand the opening on the thickened ground film, and help offset the shrinkage of the opening. For example, the above seeds can be selected as corn seeds.

[0030] The number of hole opening components 4 is determined according to the hole opening spacing requirements of the ground film operation and the size of the wheel disc 3. Figure 2 As shown, eight opening assemblies 4 are arranged in a ring shape along the axis of the wheel disc 3. The number of the opening assemblies 4 is preferably 6-12.

[0031] like Figure 3 As shown, the flip cover 43 is hinged to the outer cone shell 41 through the rotating shaft 44. With such a configuration, the flip cover 43 has the freedom to rotate around the rotating shaft 44, so that the flip cover 43 can rotate relative to the rotating shaft 44 to close or open the opening 45 of the inner cone shell 42, which is beneficial for the flip cover 43 to engage with the opening 45 of the inner cone shell 42 after the outer cone shell 41 performs a hole-making operation on the ground film, thereby smoothly completing the sowing operation.

[0032] In order to further improve the opening effect of the outer cone shell 41, as Figure 3 As shown, a wedge block 48 is provided on the back side of the outer cone shell 41. In this way, the wedge block 48 is used to further improve the opening effect of the outer cone shell 41, which is conducive to forming a T-shaped opening on the ground film. For example, the opening of the outer cone shell 41 is horizontal, and the opening of the wedge block 48 is vertical, so that a T-shaped opening is formed on the ground film.

[0033] According to a preferred embodiment of the utility model, the inner cone shell 42 is arranged in the cavity of the outer cone shell 41, and there is an equidistant interval of 2 cm between the inner cone shell 42 and the outer cone shell 41, forming a "mouth in a mouth" structure. The outer cone shell is equivalent to the extension structure of the inner cone shell to the outside. When the outer cone shell is used to perform hole-opening operations on the ground film, it has the advantage of expanding the hole opening, which is conducive to alleviating the problem of hole opening shrinkage after the thickened ground film is punctured. At the same time, when the inner cone shell is used for sowing operations, it guides the seeds, realizes accurate sowing, and avoids the occurrence of skewed sowing.

[0034] like Figure 1 As shown, a mounting frame 7 for connecting a walking device is provided on one side of the seeding frame 2. This arrangement facilitates the sowing device to be adapted to walking devices of different specifications, further improving the adaptability. For example, the mounting frame 7 is mounted on a tractor, and under the traction of the tractor, the sowing device is driven to perform hole-making and sowing operations on the thickened mulch.

[0035] like Figure 3 As shown, an elastic member 47 for providing restoring force to the flip cover plate 43 is provided between the flip cover plate 43 and the side wall of the wheel disc 3. In this way, the elastic member 47 is used to provide elastic force to the flip cover plate 43, so that the flip cover plate 43 fits the opening 45 of the inner cone shell 42 in the non-sowing state, ensuring that the opening 45 of the inner cone shell 42 is closed, avoiding the seeds from being scattered, and further improving the sowing effect.

[0036] For example, the elastic member 47 is a compression spring. One end of the compression spring is connected to the flip cover plate 43, and the other end of the compression spring is connected to the side wall of the wheel disc 3. The elastic member 47 is preferably a tower-shaped compression spring.

[0037] like Figure 3 As shown, the flip cover plate 43 is an L-shaped plate. One end of the L-shaped plate forms a seal with the opening 45 of the inner cone housing 42. The other end of the L-shaped plate is connected to the side wall of the wheel disc 3 through an elastic member 47.

[0038] In order to further improve the structural strength of the flip cover 43, as Figure 3 As shown, the bending part of the L-shaped plate is provided with a rib plate 46. In this way, the rib plate 46 is used to enhance the structural strength of the bending part of the L-shaped plate, further improving the impact resistance of the flip cover plate 43. Under the pressure of the ground, it is helpful to prevent the L-shaped plate from deforming.

[0039] When using the sowing device for mulching operation proposed in the embodiment of the utility model, the required seeds are loaded into the sowing box 1 to ensure that the number of seeds is sufficient to complete the entire sowing task. The connection and status of each component, especially the conveying channel 5, the wheel disc 3 and the opening assembly 4, are checked to ensure that they are working properly.

[0040] Install the sowing device on the tractor or other mechanical equipment, ensure that it is firmly fixed, and debug it if necessary, including adjusting parameters such as sowing depth and sowing row spacing. Start the tractor or drive the machine to make the sowing device start to move on the mulch. The seeds are transferred from the sowing box 1 to the seeding rack 2 through the conveying channel 5, and then enter the wheel disc 3. During the rotation of the wheel disc 3, the seeds are conveyed to the opening component 4 through the sowing outlet 6 on the side wall of the wheel disc 3.

[0041] As the wheel disc 3 rotates, the hole-opening assembly 4 arranged on the side wall of the wheel disc 3 contacts the ground film in turn. When the hole-opening assembly 4 contacts the ground film, the outer cone shell 41 will move downward under the action of pressure, penetrate the ground film and form a hole. In the process of the outer cone shell 41 pressing down the thickened ground film and piercing the thickened ground film, it has the advantage of expanding the orifice, which is conducive to alleviating the problem of orifice shrinkage after the thickened ground film is punctured. The flip cover plate 43 is flipped relative to the outer cone shell 41, thereby forming a propping effect on the opening on the thickened ground film. When the inner cone shell is implemented for sowing operations, it guides the seeds and realizes precise sowing. The seeds fall into the already made openings through the sowing outlet 6, avoiding the occurrence of skewed seedlings. The sowing device for ground film operations solves the problem of incomplete hole opening for thickened ground film, improves the hole opening quality, and improves sowing efficiency.

[0042] The present invention is not limited to the specific technical solutions described in the above embodiments. In addition to the above embodiments, the present invention may also have other implementation modes. For those skilled in the art, any technical solutions formed by any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
