Description

Technical Field

[0001] The invention relates to the technical field of peanut planting, in particular to a device for covering with film and punching and releasing seedlings of summer peanuts after wheat stubble. Background Art

[0002] Planting summer peanuts after wheat stubble is an important part of my country's agricultural production. However, since the sowing time coincides with unfavorable climatic conditions such as high temperature and drought in summer, if colorless transparent ground film is directly used for covering, it may cause the soil temperature to be too high, resulting in "seedling burn" phenomenon, affecting the normal growth of peanut seedlings.

[0003] Summer peanuts experience high temperatures in the early stages of their growth and development, but often experience a sharp drop in temperature during the middle and late stages. Film mulching can effectively protect summer peanut growth and development, extending the time for photosynthetic product accumulation and conversion during these stages, thereby increasing yields. Furthermore, film mulching can significantly reduce soil moisture evaporation, maintain soil moisture, improve soil physical properties, and increase soil softness, providing a stable moisture and favorable soil environment for peanut growth. Film mulching can also reduce nutrient loss and improve soil fertility. In adverse summer climatic conditions such as high temperatures, drought, or continuous rainfall, film mulching can mitigate the impact of these adverse factors on peanut growth and enhance their resilience.

[0004] Traditional film mulching planting is mostly carried out before sowing, while the post-seedling film mulching technology for summer peanuts on wheat stubble is carried out after the peanuts emerge. This innovation allows the film mulching to act more accurately on the peanut plants, avoiding problems such as emergence difficulties caused by film mulching before sowing. At the same time, post-seedling film mulching can flexibly adjust the film mulching time and method according to the growth conditions of peanuts, thereby improving the flexibility of planting management. Therefore, we propose a post-seedling film mulching and hole punching device for summer peanuts on wheat stubble to solve the above-mentioned problems. Summary of the Invention

[0058] As attached Figure 7 and attached Figure 9As shown in the figure, the output end of the electric telescopic rod 21 is installed with a support frame 22, and a third drive motor 23 is installed inside the upper part of the support frame 22, and an eccentric wheel 24 is installed at the output end of the third drive motor 23; the electric telescopic rod 21 can adjust the telescopic speed according to the vehicle speed.

[0059] A first sleeve 29, symmetrically arranged vertically, is fixed to the outer side of the stop plate 28. A second sleeve 30 is slidably connected to the interior of the first sleeve 29 and fixed to the support frame 22. The sliding contact surface between the two sleeves is provided with a friction-reducing structure, such as a sliding bearing. A dust cover can preferably be provided on the exterior of the first sleeve 29 to enclose the first and second sleeves 29, 30 and prevent dust from entering.

[0060] By adopting the above technical solution, a support frame 22 is installed at the output end of the electric telescopic rod 21, and an eccentric wheel 24 is installed at the output end of the third drive motor 23, so as to facilitate the lifting of the punching cylinder 27.

[0061] As attached Figure 8 and attached Figure 9 As shown in FIG, a connecting rod 25 is tightly fitted below the eccentric wheel 24 , and a supporting spring 26 is wound around the outside of the connecting rod 25 , and a punching cylinder 27 is fixed to the lower end of the connecting rod 25 .

[0062] By adopting the above technical solution, a connecting rod 25 is tightly fitted under the eccentric wheel 24, and a supporting spring 26 is wound around the outside of the connecting rod 25, so the structure is stable and reliable.

[0063] First, as attached Figure 1 As shown in, the frame 1 is mounted on the vehicle head, and then soil is put into the soil covering box 4, one end of the film roll 2 is pulled out, and pressed with stones or soil particles to cover the film on the bed surface, and then the vehicle drives the device to move, and the film roll 2 rotates on the frame 1 to unfold the film, and the unloading mechanism composed of the guide plate 6, the unloading plate 7, the adjusting plate 8 and the adjusting wheel 11 is opened to make the soil in the soil covering box 4 fall automatically, and the soil covers both sides of the film, suppresses the soil on the film, improves the moisture retention effect, and prevents the film from being lifted by strong winds. The adjusting rod 19, the fixed cylinder 20 and the electric telescopic rod 21 are combined to form a height adjustment mechanism, and the height of the punching cylinder 27 is adjusted according to the emergence situation, so as to adjust the punching frequency of the punching cylinder 27. The device moves, and the third drive motor 23, the eccentric wheel 24, the connecting rod 25 and the supporting spring 26 are combined to form a driving mechanism, which drives the punching cylinder 27 to move up and down to punch holes in the film to expose the peanut seedlings;

[0064] Example 1: Traditional film mulching planting is mostly carried out before sowing, which will make it difficult for peanuts to emerge. In order to solve the problem that early film mulching affects seedling emergence, the following technical solution is proposed: after wheat harvest, land preparation and stubble removal are carried out in time, and the straw is crushed and mixed into the soil using a rotary tiller or a stubble removal device to reduce the impact of the straw on subsequent sowing and film mulching. Ridges are formed according to local conditions. After sowing, herbicides such as acetochlor are used to treat the soil to reduce weed growth. After the seedlings are all grown, the device is used to cover the film immediately, and holes are punched and seedlings are released simultaneously to prevent the seedlings from being suffocated. When covering the film, ensure that the film is tightly attached to the bed surface, and the edges are pressed tightly with soil to prevent strong winds from lifting the film. After covering the film, a post-emergence herbicide is sprayed once. After the peanuts enter the flowering period, irrigation and pest control are carried out according to the weather and soil moisture conditions;

[0065] Example 2: As shown in the attached Figure 1-6 As shown in, the cover plate 5 is opened, the soil material is filled into the soil covering box 4, and the first driving motor 14 is turned on. The first driving motor 14 drives the adjusting wheel 11 installed at its output end to rotate, and a first pulley 12 is fixed below the adjusting wheel 11. The outer side of the first pulley 12 is tightly fitted with a first belt body 13. The first belt body 13 with an "8"-shaped cross section drives the first pulleys 12 symmetrically distributed on the left and right to rotate at the same time to ensure stability, and the adjusting wheel 11 drives the adjusting plate 8 engaged therewith to move. The inner end of the adjusting plate 8 is fixed with a limiting block 9, and the limiting block 9 with a "T"-shaped longitudinal section slides in the fixed plate 10 connected to the slot therewith, thereby limiting the adjusting plate 8. The adjusting plate 8 slides and drives the blanking plate 7 integrated therewith to slide. The blanking plate 7 slides below the soil covering box 4, and the soil in the soil covering box 4 automatically falls down and falls above the film, limiting the film to prevent strong winds from overturning the film.

[0066] Example 3: As shown in the attached Figure 1 , Attachment Figure 7-9 As shown in the figure, the eccentric wheel 24 installed at the output end of the third drive motor 23 is turned on, and the eccentric wheel 24 pushes the connecting rod 25 tightly fitted below it to move. The connecting rod 25 slides in the support frame 22 connected to its slot, compressing the supporting spring 26 wrapped around the outside of the connecting rod 25. When the connecting rod 25 moves, the connecting rod 25 drives the punching cylinder 27 to rise and fall, and the punching cylinder 27 is pressed on the film. The bottom of the punching cylinder 27 is a serrated structure, so that a hole is opened on the film to expose the peanut seedlings. The eccentric wheel 24 continues to rotate, and the elastic action of the supporting spring 26 pushes the connecting rod 25 to reset, and the connecting rod 25 drives the punching cylinder 27 to move. When punching, the electric telescopic rod 21 pushes the punching cylinder 27 to move, so that the punching cylinder 27 can adapt to the speed of the film and move backward to match the speed of the film when punching. After punching, it resets, and the first sleeve 29 and the second sleeve 30 installed on the outside of the limit plate 28 are slidably connected, which play a limiting role on the electric telescopic rod 21 and the punching cylinder 27 when the punching cylinder 27 moves;

[0067] Example 4: As shown in the attached Figure 1 , Attachment Figure 7-9 As shown in , when it is necessary to adjust the punching position according to the growth of the peanut seedlings, the second drive motor 18 is turned on, and the second drive motor 18 drives the second pulley 16 installed on its output end to rotate. The second belt body 17 is tightly fitted on the outside of the second pulley 16, and the second belt body 17 drives the second pulley 16 symmetrically distributed inside it to rotate. The second pulley 16 drives the adjusting rod 19 integrated below to rotate, and the adjusting rod 19 rotates in the fixed cylinder 20, and drives the limit plate 28 threadedly connected to its outside to rise and fall. The limit plate 28 slides in the fixed cylinder 20 connected to the slot therewith, and the limit plate 28 drives the electric telescopic rod 21 installed on its outside to move, and the electric telescopic rod 21 drives the punching cylinder 27 installed thereon to rise and fall, and adjusts the height of the punching cylinder 27 to adjust the hole position.
