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 holes for 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, due to unfavorable climatic conditions such as high temperature and drought in summer during sowing, if colorless and transparent mulch is directly used for covering, the soil temperature may be too high, resulting in "seedling burn" and affecting the normal growth of peanut seedlings.

[0003] The temperature is high in the early stage of summer peanut growth and development, but the temperature often drops sharply in the middle and late stages. Film mulching can effectively ensure the growth and development of summer peanuts and prolong the time for accumulation and transformation of photosynthetic products in the middle and late stages, thereby achieving the effect of increasing production. In addition, film mulching can significantly reduce the evaporation of soil moisture, keep the soil moist, improve the physical properties of the soil, increase the looseness of the soil, and provide a stable moisture environment and a good soil environment for peanut growth. Film mulching can also reduce the loss of nutrients in the soil and improve soil fertility. Under adverse climatic conditions such as high temperature and drought or continuous rainfall in summer, film mulching can reduce the impact of these adverse factors on peanut growth and improve the stress resistance of peanuts.

[0004] Traditional film mulching planting is mostly carried out before sowing, while the film mulching technology for summer peanuts after wheat stubble is carried out after the peanuts emerge. This innovation allows the film mulching to act on the peanut plants more accurately, 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 after wheat stubble to solve the above-mentioned problems. Summary of the invention

The sliding contact surfaces of the two are provided with a friction-reducing structure, such as a sliding bearing.

[0063] First, as attached Figure 1 As shown in the figure, the frame 1 is installed on the front of the vehicle, and then soil is put into the soil covering box 4, one end of the film roll 2 is pulled out, and it is pressed with stones or soil particles to cover the film on the furrow surface, and then the vehicle drives the device to move, 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 to suppress the soil on the film, improve the moisture retention effect, and prevent the film from being lifted by strong winds.

[0064] Embodiment 1: Traditional film-covered planting is mostly carried out before sowing, which will cause difficulty in germination of peanuts. In order to solve the problem that early film-covered planting affects germination, the following technical scheme is proposed: after wheat is harvested, the land is prepared and stubble is removed in time, and the straw is crushed and mixed into the soil by a rotary tiller or a stubble-removing device to reduce the impact of the straw on subsequent sowing and film-covered planting, and 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 for film covering 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 closely attached to the ridge surface, and the edge is pressed tightly with soil to prevent strong winds from lifting the film. After covering the film, spray a post-emergence herbicide once. After the peanuts enter the flowering period, irrigation and pest and disease control are carried out according to the weather and soil moisture conditions;

[0065] Embodiment 2: As attached Figure 1-6 As shown in, the cover plate 5 is opened, the soil is filled into the soil covering box 4, and the first driving motor 14 is turned on.

The adjusting wheel 11 drives the adjusting plate 8 meshing with it to move, and the inner end of the adjusting plate 8 is fixed with a limiting block 9. The limiting block 9 with a "T"-shaped longitudinal section slides in the fixed plate 10 connected to the slot therewith, which plays a limiting role on the adjusting plate 8. The adjusting plate 8 slides and drives the blanking plate 7 integrated with it 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 on the top of the film, limiting the film to prevent the film from being overturned by strong wind;

[0066] Embodiment 3: As 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 opened, and the eccentric wheel 24 pushes the connecting rod 25 tightly fitted below it to move, and the connecting rod 25 slides in the support frame 22 connected to the card slot therewith, compressing the support spring 26 wound around the outside of the connecting rod 25.

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 support 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 moves backward to be consistent with 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] Embodiment 4: As 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 at 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 the outside thereof to rise and fall, and 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 the outside thereof 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, thereby adjusting the hole opening position.
