Description

Technical Field

[0001] The present application relates to the technical field of agricultural machinery, and in particular to a sowing and film covering device. Background Art

[0002] For the sowing of crops (such as corn), common methods include broadcasting, row sowing and spot sowing. Among them, spot sowing is also called hole sowing. Since holes are opened at certain distances on the sowing rows for sowing, spot sowing can not only ensure the plant spacing and density, but also help save seeds. After sowing, in order to maintain air humidity or keep warm for the seeds, the field is generally covered with film.

[0003] The existing sowing film covering device can cover the field while walking to ensure the temperature and humidity of the air. However, since the seeds need to receive air and moisture during the growth process, the film cannot be completely closed, and the air permeability of the film needs to be increased. In addition, after the seeds break through the soil and germinate, they need to extend out of the barrier of the film in order to continue to grow smoothly. In order to make the film have good air permeability on the one hand and not hinder the normal growth of the seeds on the other hand, it is necessary to cut the corresponding film on each sowing point. For cutting the film, the existing implementation method is to use a certain film cutting tool. After the film is covered, it is cut in sequence from the starting point of sowing to form corresponding air holes and growth channels. However, this not only has a large workload, but also the position of the cut film does not necessarily correspond to the sowing point one by one, thereby affecting the growth of crops.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0026] See also Figure 1-Figure 5 The sowing film covering device provided in the present application comprises a frame 1, on which a film covering mechanism 2, a film pressing mechanism 3, a soil covering mechanism 4 and a sowing mechanism 5 are sequentially connected from front to back, and the sowing mechanism 5 is located behind the soil covering mechanism 4;

[0027] The sowing mechanism 5 includes a seed accommodating cylinder 53, one end of which is connected to the frame 1, and the other end of which is slidably connected to a seeder 52. The upper end surface of the seeder 52 is provided with a connecting rod mechanism 51 for driving the seeder 52 to reciprocate in the vertical direction.

[0028] The other end of the connecting rod mechanism 51 is connected to the frame 1 , and when the connecting rod mechanism 51 is working, it can drive the seeder 52 to periodically puncture the film 9 .

[0029] In actual use, the current film seeders are first sown and then covered with film. When watering is needed after covering with film, the planting workers are required to pierce the film where the seeds are planted one by one, which wastes the planting workers' time.

[0030] The present application arranges the sowing mechanism 5 behind the film covering mechanism 2. After the film covering is completed, the film covering the required planting position is punctured by the seeder 52 and the planting is completed at the same time, ensuring that the seed planting position corresponds to the position where the film 9 is broken, which is convenient for watering the seeds later.

[0031] Specifically, when planting, the present application firstly places the seeds in the seed holding tube 53, and the other end of the seed holding tube 53 is slidably connected with the seeder 52 to ensure that the seeds can slide from the seed holding tube 53 to the seeder 52. The top of the seeder 52 is driven by the connecting rod mechanism 51 to reciprocate in the vertical direction. When the seeder 52 moves to the ground, the film 9 is pierced and extended into the soil to plant the seeds. Under the action of the connecting rod mechanism 51, the next planting is carried out;

[0032] The connecting rod mechanism 51 drives the seeder 52 to reciprocate once, and the seeds are planted once, that is, the seeds can be planted at equal intervals.

[0033] In the above embodiment, the film covering mechanism 2 includes two sets of inverted L-shaped connecting plates 21 and a film roller 24. The ends of the two short sides of the two sets of inverted L-shaped connecting plates 21 are respectively connected to the outer side wall of the frame 1. The ends of the two long sides of the two sets of inverted L-shaped connecting plates 21 are rotatably provided with a first rotating shaft 22. The first rotating shaft 22 is sleeved with a film roller 24. The film roll is sleeved on the film roller 24, and the film 9 is pulled out to cover the surface of the field.

[0034] The long side ends of the two sets of inverted L-shaped connecting plates 21 are respectively provided with first through holes 25 , and the first rotating shaft 22 passes through the first through holes 25 . Both ends of the first rotating shaft 22 are fixed by first limiting rings 23 , and the first limiting rings 23 are threadedly connected to the first rotating shaft 22 .

[0035] The film pressing mechanism 3 includes a top plate 31, a first side plate 32 and a second side plate 35. The top plate 31 is mounted above the frame 1. The first side plate 32 and the second side plate 35 respectively extend two other sets of first connecting frames 33 and second connecting frames 34 parallel thereto. Film pressing wheels 38 are rotatably arranged between the first connecting frames 33, the second connecting frames 34 and the first side plate 32 and the second side plate 35.

[0036] Specifically, the film pressing wheel 38 is connected between the first side plate 32 and the first connecting frame 33 , the second side plate 35 and the second connecting frame 34 through the second rotating shaft 36 , and is limited by the second limiting ring 37 .

[0037] In a specific use process, after the laminating mechanism 2 completes the laminating work, the laminating wheels 38 of the laminating mechanism 3 move on both sides of the film 9 to limit the film 9 so as to facilitate the film 9 to fit with the ground.

[0038] The soil covering mechanism 4 includes two sets of symmetrical second connecting plates 43 and a soil covering shovel 42. One end of the two sets of second connecting plates 43 is connected to the outer side walls of the first side plate 32 and the second side plate 35 respectively. The upper end surface of the soil covering shovel 42 is connected to the other end of the second connecting plate 43 through two sets of first connecting rods 41.

[0039] The lower end surface of the soil covering shovel 42 extends into the soil. When the sowing film covering mechanism 2 moves forward, the soil is scooped up and covered on both sides of the film 9 to prevent the film 9 from being blown up by the wind.

[0040] The above is the prior art, which is a feasible method of the present application. The present application can also be used in conjunction with other mulching machines for sowing.

[0041] Furthermore, the frame body 1 includes a first frame 11 and a second frame 12, and the first frame 11 and the second frame 12 are arranged in parallel. The first frame 11 and the second frame 12 are connected to each other at one end close to the sowing mechanism 5 by a first connecting plate 7. A support plate 10 is vertically provided on this end of the first frame 11, and a second connecting rod 55 is rotatably provided on the support plate 10. A support frame 8 for supporting the second connecting rod 55 is provided on the first connecting plate 7. The surface where the support frame 8 contacts the second connecting rod 55 is an arc-shaped surface, which just drags the cylindrical surface of the support rod 8 without affecting the rotation of the second connecting rod 55.

[0042] In addition, a round rod 6 is provided between the first frame 11 and the second frame 12 at one end away from the sowing mechanism 5, so as to facilitate pulling the sowing film covering device when the sowing film covering device is working.

[0043] In addition, a motor 54 is provided on the support plate 10 , and a housing of the motor 54 is connected to the outer side of the support plate 10 for driving the second connecting rod 55 to rotate.

[0044] The first connecting plate 7 is provided to ensure stability in the connection between the first frame 11 and the second frame 12 , and the supporting frame 8 is provided to support the sowing mechanism 5 .

[0045] Furthermore, the connecting rod mechanism 51 includes a first rotating rod 511 , one end of which is fixedly connected to the second connecting rod 55 via a connecting ring, and the other end of the first rotating rod 511 is hinged to the second rotating rod 512 .

[0046] The rotation of the second connecting rod 55 drives the first rotating rod 511 to rotate in a circle, and the circular motion of the first rotating rod 511 drives the second rotating rod 512 to move.

[0047] Further, the seeder 52 includes a hollow sowing cylinder 520, and the top end of the sowing cylinder 520 is hinged to the second rotating rod 512. The top end of the sowing cylinder 520 is closed.

[0048] In a possible implementation, the movement of the second rotating rod 512 can drive the seeding cylinder 520 to move.

[0049] Furthermore, the seed containing cylinder 53 includes a cylinder body 531 and a sliding tube 532. The sliding tube 532 is arranged on one side of the bottom of the cylinder body 531. One end of the sliding tube 532 is fixedly connected to the cylinder body 531 and the internal spaces of the two are connected. The other end of the sliding tube 532 is inclined downward and extends toward the sowing cylinder 520. The end of the sliding tube 532 away from the cylinder body 531 is slidably connected to the sowing cylinder 520 along the vertical direction.

[0050] In one possible implementation, the seeds to be sown can be stored in advance in the cylinder body, and the seeds can slide from the cylinder body 531 into the slide tube 532, and then slide from the slide tube 532 into the sowing cylinder 520. When the sowing cylinder 520 pierces the film and inserts into the soil, the seeds will slide along the sowing cylinder into the field.

[0051] The sliding tube 532 can be tilted downward to ensure that the seeds slide smoothly in the sliding tube 532 , thereby preventing excessive resistance and accumulation of seeds in the sliding tube 532 .

[0052] Furthermore, the seeding cylinder 520 includes an outer cylinder 521 and an inner cylinder 523. A sliding groove 525 is provided on the side of the outer cylinder 521 close to the sliding tube 532, which runs from top to bottom and penetrates the side wall of the outer cylinder 521. The sliding tube 532 is slidably inserted in the sliding groove 525.

[0053] An opening 524 is provided on the side wall of the inner cylinder 523; when the sowing cylinder 520 is inserted into the soil for sowing, the opening 524 on the inner cylinder 523 is aligned with the lower end of the slide tube 532, and at other times, the lower end of the slide tube 532 is in contact with one of the side walls of the inner cylinder 523 in the vertical direction.

[0054] In a possible implementation, a slide tube 532 is inserted into the slide groove 525 to limit the movement direction of the seeding barrel 520, that is, the rotation of the second connecting rod 55 drives the first rotating rod 511 to rotate in a circle, the first rotating rod 511 drives the second rotating rod 512 to move in a circle, and the movement of the second rotating rod 512 can drive the seeding barrel 520 to move. Since the slide tube 532 limits the seeding barrel 520, the seeding barrel 520 can only reciprocate in the vertical direction.

[0055] When the sowing tube 520 moves in the vertical direction, only when the opening 524 on the inner tube 523 of the sowing tube 520 cooperates with the lower end of the sliding tube 532, the seeds in the sliding tube 532 can slide from the sliding tube 532 into the sowing tube 520 and be planted in the field, thereby achieving the planting of seeds at equal intervals. At other times, the lower end of the sliding tube 532 fits with one of the side walls of the inner tube 523 in the vertical direction, so that the seeds can be stored in the sliding tube 532 to avoid seed waste.

[0056] Furthermore, the bottom of the seeder 52 is in a conical structure, and a through hole 522 is provided on the outer peripheral surface of the conical seeder 52, and the diameter of the through hole 522 is not less than the diameter of the seed.

[0057] In one possible implementation, when the cone-shaped seeder 52 reduces its contact with the film 9, it is convenient to puncture the film 9. After the seeder 52 punctures the film 9, the seeder 52 goes deeper into the ground, and the soil will enter the seeder 52 along the circular holes on the outer surface of the seeder 52, thereby loosening the soil. At the same time, the soil in the seeder 52 will wrap the seeds that fall to the ground from the seeder 52. When the seeder 52 moves upward, the seeds fall with the soil, thereby planting.

[0058] The actual use process of the seeding film covering machine of the present application is as follows: the whole device is pulled forward, the film covering mechanism 2 covers the surface of the field, and then the two film pressing wheels 38 of the film pressing mechanism 3 press the two sides of the film 9 covering the ground surface, and the covering shovel 42 of the film covering mechanism 2 scoops up the soil outside the film 9 and covers the two sides of the film 9 to compact the film 9. The seeder 52 of the sowing mechanism 5 reciprocates under the action of the connecting rod mechanism 51. When the seeder 52 moves up and down to correspond to the opening 524 thereon and the outlet of the slide tube 532 of the seed receiving tube 53, the seed slides from the seed receiving tube 53 into the seeder 52 along the slide tube 532. At this time, the conical structure at the bottom of the seeder 52 The structure just punctures the film 9 on the ground surface and enters into the soil. The soil in the ground will enter into the conical structure at the end of the seeder 52 along the circular hole at the bottom of the seeder 52, and mix with the seeds already in the conical structure of the seeder 52. The seeder 52 moves upward. At this time, the soil that enters the circular hole during the descent of the seeder 52 falls from the seeder 52 to the ground together with the seeds, and covers the seeds, thereby achieving seed sowing. Only when the seeder 52 moves downward to the point where the opening 524 of the inner tube 523 corresponds to the lower end of the sliding tube 532 of the seed holding tube 53, will the seeds slip from the seed holding tube into the seeder 52 and then be planted in the soil, thereby achieving the planting of seeds in the soil at equal intervals.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
