Description

一种滚切式小麦少耕施肥播种机 A rolling-cut wheat seeder with less tillage and fertilization

技术领域technical field

本实用新型涉及一种滚切式小麦少耕施肥播种机,属农业播种机械技术领域。The utility model relates to a rolling-cut wheat seeder for less tillage and fertilization, which belongs to the technical field of agricultural seeding machinery.

背景技术Background technique

小麦、玉米是我国北方地区主要的农作物,传统的耕作制度是秋季玉米秸秆还田耕整地后播种小麦。随着水资源的日益短缺和节水农业技术的发展,近年来新兴的玉米秸秆覆盖技术改善了土壤的水分状况,该技术可保蓄田间土壤水分,降低土壤水分消耗速度,减少棵间蒸发量,提高水资源利用效率,玉米秸秆覆盖技术就像一条拦水坝,将自然降水全部贮蓄在种植行内,这不仅控制了水土流失,还能挡风积雪,减少土壤水分蒸发。现有的小麦带状少耕播种机,一般经过两道工序,首先将玉米秸秆粉碎,然后再进行少耕施肥播种,采用活动甩刀或锤片式粉碎秸秆,使用效果尚好,但动力消耗大,震动剧烈,且粉碎刀不能入土作业;旋耕刀具有较强的破茬入土能力,但对地表秸秆的破碎效果不理想,容易堵塞机具。因此采用粉碎刀或旋耕刀装置使拖拉机一次进地作业完成小麦少(免)耕播种的种植效果不理想。Wheat and corn are the main crops in northern my country. The traditional farming system is to sow wheat after returning corn stalks to the field for plowing in autumn. With the increasing shortage of water resources and the development of water-saving agricultural technology, the emerging corn straw mulching technology has improved the soil moisture status in recent years. This technology can preserve the soil moisture in the field, reduce the rate of soil moisture consumption, and reduce the evaporation between trees. , Improve the efficiency of water resource utilization. The corn straw mulching technology is like a dam, which stores all the natural precipitation in the planting row. This not only controls soil erosion, but also blocks wind and snow and reduces soil water evaporation. The existing wheat strip-shaped low-tillage seeder generally goes through two processes. First, the corn stalks are crushed, and then the low-tillage fertilization and seeding are carried out. The movable knife or hammer is used to crush the straw. The effect is good, but the power consumption is large. , the vibration is severe, and the crushing knife cannot penetrate into the soil; the rotary tiller has a strong ability to break stubble into the soil, but the crushing effect on the surface straw is not ideal, and it is easy to block the machine. Therefore adopt crushing knife or rotary plowing knife device to make tractor once into the ground operation and finish the planting effect of wheat less (free) tillage sowing is unsatisfactory.

发明内容Contents of the invention

本实用新型的目的在于提供一种与小型拖拉机配套的既能粉碎地表直立长秸秆,又能同时破茬,动力消耗低,小麦平播的施肥播种机,一次性完成田间玉米粉碎破茬、开沟、施肥、播种、覆土、镇压等多项作业。The purpose of this utility model is to provide a kind of fertilizing and seeding machine which is matched with a small tractor and can not only crush the upright long straw on the ground surface, but also break the stubble at the same time, has low power consumption, and flat sows wheat. Ditching, fertilization, sowing, covering soil, suppression and many other operations.

本实用新型的技术方案是这样实现的:这种滚切式小麦少耕施肥播种机,基本结构包括与拖拉机挂接的机架、机架上设置的种箱、肥箱,机架下部设置的排种管,机架后挂接覆土轮和镇压辊构成,其特征在于:播种机排种管前方设置滚切刀。The technical scheme of the utility model is realized in the following way: the basic structure of this roll-cut type wheat seeder with less tillage and fertilization includes a frame connected with a tractor, a seed box and a fertilizer box arranged on the frame, and a The seeding pipe is composed of a cover wheel and a pressing roller mounted behind the frame, and is characterized in that a rolling cutter is arranged in front of the seeding pipe of the seeder.

所述的滚切式小麦少耕施肥播种机,所述的滚切刀为多个T形锄铲式刀头、刀杆径向均布在滚切刀轴上构成。In the rolling cutting type wheat seeder with less tillage and fertilization, the rolling cutter is composed of a plurality of T-shaped hoe-shovel cutter heads, and the cutter bars are evenly distributed radially on the rolling cutter shaft.

所述的滚切式小麦少耕施肥播种机,所述的滚切刀在滚切轴轴向间隔分布,中间设置免耕带。In the roll cutting type wheat seeder with less tillage and fertilization, the roll cutters are arranged at intervals in the axial direction of the roll cutting shaft, and a no-tillage belt is arranged in the middle.

所述的滚切式小麦少耕施肥播种机,所述的滚切刀前方设置有秸秆压辊。In the rolling-cutting type wheat seeder with less tillage and fertilization, a straw pressing roller is arranged in front of the rolling cutter.

所述的滚切式小麦少耕施肥播种机,所述的肥箱内设置施肥板延伸至滚切刀与秸秆压辊之间。In the roll-cut type wheat seeder with less tillage and fertilization, a fertilization plate is arranged in the fertilizer box and extends between the roll cutter and the straw pressing roller.

所述的滚切式小麦少耕施肥播种机,所述的播种机还包括拖拉机前方设置的玉米秸秆分禾器。The rolling-cut wheat seeder with less tillage and fertilization further includes a corn stalk divider arranged in front of the tractor.

本实用新型的技术进步效果表现在:The technological progress effect of the present utility model is manifested in:

1、与20马力小型拖拉机配套,拖拉机一次进地完成田间播种带玉米秸秆粉碎、破茬、施肥、开沟、播种、覆土、镇压等多项作业,属少耕播种。1. It is matched with a 20-horsepower small tractor. The tractor can complete multiple operations such as corn stalk crushing, stubble breaking, fertilization, ditching, sowing, soil covering, and suppression in the field at one time. It belongs to less-tillage sowing.

2、种肥箱分开设置,可一次作业足量施用作物生长期所需全部缓释肥料。肥料在耕作前经施肥板直接洒施在压秸辊与滚切刀之间的地表上,经滚切刀施耕地面与土壤混合,绝不烧苗。2. The seed fertilizer boxes are set separately, which can apply all the slow-release fertilizers needed for the crop growth period in one operation. Before tillage, the fertilizer is directly sprinkled on the surface between the straw roller and the rolling cutter through the fertilizing plate, and the ground is mixed with the soil through the rolling cutter, and the seedlings are never burned.

3、采用“T”形锄铲式滚切刀粉碎播种带上的秸秆,既能粉碎地表直立的长秸秆,又能同时破茬,破茬深度5-6cm,满足小麦播种的种床深度。3. Use the "T" shaped hoe-shovel-type rolling cutter to crush the straw on the sowing belt. It can not only crush the long upright straw on the ground, but also break the stubble at the same time. The stubble breaking depth is 5-6cm, which meets the seedbed depth of wheat sowing.

4、采用压持切碎方式作业,其秸秆粉碎效果优于现行的活动甩刀或锤片式秸秆粉碎机。滚切刀前方设置的秸秆压辊既起限深的作用,又能压住秸秆,其后的滚切刀旋转再将地表的秸秆和地下的根茬一齐切碎,并与土壤混合。4. The operation of pressing and chopping is adopted, and the straw crushing effect is better than that of the current movable knife or hammer straw grinder. The straw pressing roller set in front of the hob cutter not only plays the role of depth limit, but also can press the straw, and then the hob cutter rotates to chop the straw on the surface and the root stubble under the ground, and mix it with the soil.

5、采用间隔设置滚切刀播种带少耕作业,未耕地占作业幅宽的41.4%,可节省拖拉机动力,能实现与20马力小拖配套的少耕播种作业。5. The hob cutter sowing belt is set at intervals for less-tillage operation, and the uncultivated land accounts for 41.4% of the operation width, which can save tractor power and realize the less-tillage sowing operation matched with a 20-horsepower small tractor.

6、可实现小麦平播,开沟器在秸秆粉碎并耕作的地方通过,通过性好,有效地结决了机具的堵塞问题。6. It can realize flat sowing of wheat, and the ditch opener can pass through the place where the straw is crushed and plowed, and the passability is good, which effectively solves the problem of machine blockage.
