Description
技术领域 technical field
本发明涉及农业机械技术领域，具体涉及一种西北旱作区的可调式马铃薯全膜双垄沟施肥播种覆膜覆土联合作业机。 The invention relates to the technical field of agricultural machinery, in particular to an adjustable potato full-film double-furrow fertilization, seeding, film-covering and soil-covering combined operation machine in the dry farming area of Northwest China.
背景技术 Background technique
马铃薯全膜双垄沟播栽培技术是通过按带幅起大小垄，实施全地面覆盖，集保墒、集雨、增温、增产为一体的一项适宜于我国北部干旱半干旱地区的抗旱种植技术。其主要优点是：通过在大小垄上全部覆盖地膜，充分收集马铃薯生长期间的全部降雨，有效解决了旱作区因春旱严重影响播种的问题，从而保证马铃薯正常出苗；能最大限度地保蓄马铃薯生长期间的全部降雨，减少土壤水分的无效蒸发，保证马铃薯生育期内的水分供应；早期能够提高地温，增加有效积温，延长马铃薯生育期，有利中晚熟品种发挥生产潜力，具有明显的增产效果。目前，广泛采用全膜双垄沟铺膜机铺膜，人工点播的种植方式，劳动强度大，播种深度达不到农艺要求，进而影响马铃薯品质。国内目前马铃薯全膜双垄沟播种机有固定作业深度，变速箱提供整机传动动力，作业不够精确，作业效果无法达到需求。取土覆土装置不能调节限制了膜上压土和覆膜时地膜压边时的用土需求量。对马铃薯膜上压一定量土可提高马铃薯破膜出土能力，根据不同地况，膜上压土厚度不同，可对其进行优化。地轮高度决定播种作业深度，在不同土壤条件下播种深度可决定出苗率，同时，由地轮传动可对取种量进行确定，达到均匀播种的效果。 Potato full-film double-furrow sowing cultivation technology is a drought-resistant planting technology suitable for arid and semi-arid areas in northern my country by raising large and small ridges according to the width, implementing full ground coverage, and integrating moisture conservation, rain collection, temperature increase, and production increase. Its main advantages are: by covering all the large and small ridges with plastic film, fully collecting all the rainfall during the potato growth period, effectively solving the problem that the sowing is seriously affected by the spring drought in dry farming areas, thereby ensuring the normal emergence of potatoes; All the rainfall during the potato growth period can reduce the ineffective evaporation of soil moisture and ensure the water supply during the potato growth period; in the early stage, the ground temperature can be increased, the effective accumulated temperature can be increased, and the potato growth period can be extended, which is conducive to the late-maturing varieties to develop their production potential and has a significant increase in production. . At present, the full-film double-furrow film-laying machine is widely used, and the planting method of manual on-demand planting is labor-intensive, and the sowing depth cannot meet the agronomic requirements, which in turn affects the quality of potatoes. At present, the domestic potato full-film double-furrow planter has a fixed operating depth, and the gearbox provides the driving power of the whole machine. The operation is not precise enough, and the operation effect cannot meet the demand. The soil taking and covering device cannot be adjusted, which limits the soil demand when pressing the soil on the film and pressing the edge of the film when covering the film. Pressing a certain amount of soil on the potato film can improve the ability of the potato to break the film and unearth. According to different land conditions, the thickness of the soil on the film is different, and it can be optimized. The height of the ground wheel determines the depth of the sowing operation, and the sowing depth can determine the emergence rate under different soil conditions. At the same time, the amount of seeds taken can be determined by the transmission of the ground wheel to achieve the effect of uniform sowing.

At the same time, driven by the ground wheel shaft 16, the power is transmitted through the spoon sprocket 7 As for the spoon chain seed meter 6, since the spoon chain seed meter 6 is linked with the ground wheel shaft 16, the ground wheel transmission can ensure the stability of the spoon chain seed meter 6 for the amount of seeds taken, and achieve the effect of uniform sowing. Driven by the spoon sprocket 7, the spoon chain type seed metering device 6 takes out the potato seeds from the seed box 10, falls through the seed metering groove 8, and the seeds reach the rear of the ditch opener 9 and fall into the seed bed, which is located behind the ditch opener 9. The shaper 24 in the inner side of the frame 26 bottom carries out covering soil and ridges, and the film-covering frame 25 covers the ridges that the shaper 24 has played. Simultaneously, digging shovel 2 scoops up the soil, and places it on the soil conveyer belt 1, carries out edge pressing and pressing soil after the potato seed mulching film respectively through soil chute 4 upper and lower two layers of chutes, reaches sowing, deep The effect of the integrated operation of applying chemical fertilizers, ridging, suppressing and shaping, full film mulching, and lifting and covering soil.
调节杆装置5可对挖掘铲2的深度进行调节，通过控制挖土量，进而调节膜上覆土的厚度。地垄传动系统15上连接高度调节杆18，可调节整机高度，进而调节开沟器9和开沟轮3的深度，影响到播种深度。播种系统由行走轮14转动带动地轮轴16转动，可实现播种与化肥深播之间的同步进行，不受机器行走速度的影响，可以实现均匀播种和施肥，实现播种的优化。 The adjusting rod device 5 can adjust the depth of the excavating shovel 2, and then adjust the thickness of the covering soil on the membrane by controlling the excavation amount. The height adjustment rod 18 is connected on the ridge transmission system 15, which can adjust the height of the whole machine, and then adjust the depth of the ditch opener 9 and the ditch wheel 3, which affects the sowing depth. The sowing system is driven by the rotation of the walking wheel 14 to rotate the ground wheel shaft 16, which can realize the synchronization between sowing and deep sowing of chemical fertilizers, and is not affected by the walking speed of the machine. It can realize uniform sowing and fertilization, and realize the optimization of sowing.
