Description

Technical Field

[0001] The utility model belongs to the technical field of sowing, and in particular relates to a manual sowing device. Background Art

[0002] In the agricultural production process, sowing is an important part of the production operation. Specifically, by sowing crop seeds in the fields at a specific time, the first step of agricultural production is completed. The entire agricultural production process is completed with the growth and development of seeds and the maturity and harvesting of crop plants.

[0003] At present, sowing is mainly done through mechanized sowing. Specifically, mechanized sowing not only greatly improves the sowing efficiency, but also the sown seeds are evenly distributed, which facilitates increasing planting efficiency.

[0004] However, mechanized operations also have certain limitations. For example, mechanized seeding can only be performed on large, flat land, mostly vast plains. In hilly areas, especially those with complex terrain, such as those with severely uneven and confined areas, mechanized equipment is completely unable to operate. This can manifest itself in the inability of mechanical equipment to enter the work area or operate normally in areas with severely uneven and confined areas.

[0005] Therefore, in areas with limited land and severely uneven terrain, manual seeding is the only option. However, this method also has obvious disadvantages. Firstly, manual seeding is laborious and time-consuming, and secondly, the seeds sown by manual seeding are unevenly distributed in the field.

[0006] Therefore, in complex terrain environments, it is of great significance to improve sowing efficiency by using a sowing equipment with high sowing efficiency, high flexibility and good sowing effect. Utility Model Content

[0007] Based on the above background, the purpose of the present invention is to provide a manual sowing device.

[0008] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0009] A manual sowing device includes a roller mechanism, wherein the roller mechanism includes a wheel frame structure and rollers mounted on both sides of the wheel frame structure, wherein a rotating shaft rotatably connected to the wheel frame structure is fixedly connected between the rollers;

[0010] The manual sowing device also includes a plurality of seed box assemblies fixedly mounted on the top of the wheel frame structure, and a plurality of rotating flying assemblies corresponding to the seed box assemblies are fixedly connected to the rotating shaft;

[0011] The spinning assembly includes a mounting sleeve fixedly connected to the rotating shaft, and a plurality of flying plates are fixedly connected to the outer wall of the mounting sleeve;

[0012] During the rolling process of the pushing roller mechanism, the flying plate rotates, and the seeds falling from the seed box assembly hit the flying plate and are ejected through the rotating flying plate; by changing the pushing speed and pushing direction, the force and direction of the flying plate hitting the seeds are synchronously adjusted to change the landing point of the seeds after sowing.

[0013] Preferably, the wheel frame structure includes wheel seats spaced apart in front and back, and the rotating shaft is rotatably connected between the wheel seats.

[0014] Preferably, the wheel frame structure further comprises a U-shaped connecting beam fixedly connected between the tops of the wheel seats;

[0015] The seed box assembly is fixedly mounted on the U-shaped connecting beam.

[0016] Preferably, the seed box assembly includes a seed storage box, the bottom of the seed storage box is connected to a seed discharge tube, and the seed discharge tube faces the fly plate.

[0017] Preferably, the bottom of the seed storage box is connected to two seed discharge pipes arranged symmetrically on the left and right;

[0018] The seed discharging tube includes a lower inclined tube portion facing the fly plate, and the lower inclined tube portion is integrally formed with an upper inclined tube portion;

[0019] The upper inclined tube portion is communicated with the bottom of the seed storage box.

[0020] Preferably, the seed storage box includes a cylindrical portion, the cylindrical portion is integrally formed with a tapered portion, the tapered portion is integrally formed with a curved portion, and the lower inclined tube portion is connected to the curved portion.

[0021] Preferably, the seed storage box is fixedly mounted on the top of the U-shaped connecting beam through a height adjustment structure;

[0022] The height adjustment structure includes a fixed sleeve fixedly connected to the top position of the U-shaped connecting beam, the fixed sleeve is threadedly connected to an adjusting screw, and the adjusting screw is fixedly connected to the bottom position of the curved part.

[0023] Preferably, a plurality of elastic impact members are fixedly connected to the upper end of the seed storage box. Seeds are stored in the seed storage box, and the elastic impact members elastically impact the seed storage box to assist in discharging the seeds.

[0024] Preferably, the elastic impact member comprises a spring fixedly connected to the seed storage box, and a rubber impact ball is fixedly connected to the bottom of the spring.

[0025] Preferably, a pushing handle is fixedly connected to the right side wall of the wheel seat.

[0026] The utility model has the following beneficial effects:

[0027] During the sowing operation, the operator pushes the entire device. As the roller rotates, the rotating shaft rotates synchronously. This causes the fly plate to rotate, and seeds falling from the seed box assembly impact the fly plate and are ejected by the rotating fly plate. This method allows simultaneous sowing from multiple seed box assemblies. The rotating fly plate also disperses the seeds, increasing the sowing range and uniformity of seed distribution.

[0028] By increasing the pushing speed, the fly plate's rotation speed increases, thereby increasing the impact force and improving the uniformity of seed dispersion. Furthermore, during the sowing process, by pushing back and forth, the rotation axis switches between clockwise and counterclockwise, which in turn continuously changes the fly plate's rotation direction, changing the direction of the seeds' scattering upon impact, further increasing the sowing range and improving sowing uniformity.

[0029] 2. The height of the seed box assembly can be adjusted to change the speed at which the seeds hit the flying plate during the sowing process, thereby further adjusting the landing point of the seeds during the sowing process and further achieving uniform sowing.

[0040] Example 1

[0041] like Figure 1-5 As shown, a manual sowing device includes a roller mechanism, which includes a wheel frame structure and rollers 1 installed on both sides of the wheel frame structure. A rotating shaft 2 rotatably connected to the wheel frame structure is fixedly connected between the rollers 1.

[0042] Specifically, the wheel frame structure includes wheel seats 11 spaced apart in front and back, with the rotating shaft 2 rotatably connected between the wheel seats 11 (bearings rotatably connected to the rotating shaft 2 are mounted on the wheel seats 11 in a conventional manner disclosed in the prior art). The wheel frame structure also includes a U-shaped connecting beam 12 fixedly connected between the tops of the wheel seats 11.

[0043] At the same time, the right side wall of the wheel seat 11 is respectively fixedly connected with a push handle 4. During operation, the operator pushes the push handle 4 to push the entire device to sow in an uneven and narrow field.

[0044] In order to realize the sowing operation and disperse the sown seeds quickly, efficiently and evenly during the sowing operation, the above-mentioned manual sowing device also includes a plurality of seed box assemblies 5 fixedly installed at the top position of the wheel frame structure (specifically, the seed box assemblies 5 are fixedly installed on the U-shaped connecting beam 12), and a plurality of rotating flying assemblies 3 corresponding to the seed box assemblies 5 are fixedly connected to the rotating shaft 2.

[0045] Specifically, the rotating fly assembly 3 includes a mounting sleeve 31 fixedly connected to the rotating shaft 2 , and a plurality of fly plates 32 are fixedly connected to the outer wall of the mounting sleeve 31 ; the fly plates 32 are made of elastic plastic material.

[0046] During operation, the operator pushes the entire device. As the roller 1 rotates, the rotating shaft 2 rotates synchronously. At this time, the fly plate 32 rotates, and the seeds falling from the seed box assembly 5 impact the fly plate 32 and are ejected by the rotating fly plate 32. This method allows simultaneous seeding through multiple seed box assemblies 5. Furthermore, the seeds are dispersed by the rotating fly plate 32, thereby increasing the sowing range and the uniformity of seed distribution.

[0047] Furthermore, the above device adjusts the rotation speed of the ejection plate 32 according to the seed placement speed (seeds of different particle sizes have different placement speeds) during the sowing process, thereby adjusting the force of the seed impact. For example, when the seed placement speed is fast (small-particle seeds, such as rapeseed seeds), the pushing speed is increased, and the rotation speed of the ejection plate 32 is increased. This increases the impact force and improves the uniformity of sowing and dispersion.

[0048] At the same time, during the sowing process, by pushing back and forth, the rotating shaft 2 is switched between clockwise and counterclockwise, and then the rotation direction of the flying plate 32 is constantly changed, so as to change the flying direction of the seeds when the material hits it, thereby further increasing the sowing range and improving the uniformity of the sowing.

[0049] The above method changes the landing point of seeds after sowing, achieving uniform sowing.

[0050] Example 2

[0051] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 1, the lower seed box assembly 5 includes a seed storage box 51 (the shape of the seed storage box 51 is: the seed storage box 51 includes a cylindrical portion, the cylindrical portion is integrally formed with a conical portion, and the conical portion is integrally formed with a curved portion), and the bottom of the seed storage box 51 is connected to a seed discharge tube 52, and the seed discharge tube 52 faces the fly plate 32.

[0052] Specifically, the bottom of the seed storage box 51 is connected to two seed discharge tubes 52 symmetrically arranged on the left and right; the seed discharge tubes 52 include a lower inclined tube portion facing the fly plate 32 (the lower inclined tube portion is connected to the curved portion), and the lower inclined tube portion is integrally formed with an upper inclined tube portion (the upper inclined tube portion is connected to the bottom of the seed storage box 51); the lower inclined tube portions are respectively facing the fly plate 32.

[0053] This method enables the seeds in the lower row to hit the bounce plate 32 from both sides, thereby achieving synchronous sowing in different directions.

[0054] Example 3

[0055] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 2, the seed storage box 51 is fixedly installed on the top of the U-shaped connecting beam 12 through a height adjustment structure; the height adjustment structure includes a fixed sleeve 54 fixedly connected to the top position of the U-shaped connecting beam 12, and the fixed sleeve is threadedly connected to an adjusting screw 53, and the adjusting screw 53 is fixedly connected to the bottom position of the curved part.

[0056] The height of the seed storage box 51 is adjusted by adjusting the screw, thereby changing the distance between the seed discharging tube 52 and the ejection plate 32, thereby changing the speed at which the seeds fall and hit the ejection plate 32 (in the process of seed feeding, speed is related to potential energy. The greater the height, the greater the potential energy, and the greater the speed when hitting the ejection plate 32. The ejection speed during sowing is different. In this way, adjustment according to the sowing situation is achieved. For example, if the sowing density is small, the height of the seed storage box 51 is increased to increase the potential energy. By utilizing the law of conservation of energy, the seeds often land farther away after being ejected.

[0057] Example 4

[0058] like Figure 1-5 As shown, this embodiment builds on the structure of Example 3, with several elastic impact members 55 fixedly connected to the upper end of the seed storage box 51. The seeds stored in the seed storage box 51 are elastically impacted by the elastic impact members, assisting in seed discharge. The elastic impact members 55 include a spring 551 fixedly connected to the seed storage box 51, with a rubber bumper 552 fixedly connected to the bottom of the spring 551.

[0059] Specifically, because the entire device operates on uneven terrain, the spring 551 and rubber ball 552 continuously impact the seed storage box 51 during the swinging process, thereby assisting the seed discharge from the seed storage box 51. This is especially true for seeds with a light texture and poor fluidity, which can easily become clogged and trapped in the seed box during sowing, preventing smooth discharge. The impact increases the looseness of the seeds, thereby assisting in the discharge of seeds.

[0060] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
