Abstract
An inclined rotary-tillage paddy field grass burying machine belonging to the field of agricultural engineering comprises rotary-tillage cutters which are transversely and orderly arranged, a side gear box, a middle gear box, a gimbal, a three-point hanger bracket and the power output shaft of a tractor. The power output shaft of the tractor is connected with the gimbal by a spline, the gimbal is connected with the middle gear box by a spline, the middle gear box is connected with the side gear box by a flat key, and the side gear box is connected with the cutters by flat keys. The inclined rotary-tillage cutters form an angle of fifteen to twenty-eight degrees with the wheel shaft of the tractor, the side cutting blades of the cutters face to the right of the moving direction of the tractor, and each cutter head is provided with two rotary-tillage cutters, the phase difference of which is 180 degrees. A phase difference B which is between 30-120 degrees exists between each rotary-tillage cutter and the corresponding rotary-tillage cutter on the adjacent cutter head, and the phase difference B is decided by the principle that the rotary-tillage cutters can mutually break the constraints of soil on the sides to destroy the soil by pulling. The invention has good grass removing performance and is more suitable for operation in paddy fields.
Description
Technical field
The invention belongs to the agricultural engineering field, refer in particular to inclined rotary tillage paddy field straw burying machine.
Background technology
About 6,670,000 hm2 of China's rice cornfield area, a large amount of wheat straws are recycling to be problem demanding prompt solution.Along with the raising of living standards of the people, wheat straw has withdrawed from the row of farmers''s main fuel, and the wheat straw deep processing development utilizes approach narrow, and it is one that burnt or abandon and go to river that most peasant households can only take, and both wasted resource, brings very serious environmental to pollute again.According to the statistical data of China Meteorological Administration, the 2003 crop straw burning amounts of being only Jiangsu Province just reach 1029 * 104 tons.Annual summer harvest season, government department all will issue to prohibit burns announcement, but effect is difficult as people's will, the indivedual peasant households in some areas is always arranged because of the careless initiation fire of steamed dumplings, traffic accident every year, jeopardizes field crop and people life property safety.On the other hand, because a large amount of chemical fertilizer that uses hardens soil organic matter reduction, physicochemical property variation and the face of land.
Wheat straw waste is a valuable natural resources.How improving the recycling efficient of rice wheat crop rotation district wheat straw, recover soil fertility and alleviate the resource and environment pressure that brings because of crop straw burning, is the problem that governments at all levels and agricultural machinery and agronomy scientific research personnel press for solution in a short time.
Rotary ploughing machine for covering grass integrates chaffcutter, buries grass, rotary tillage, hack function, and is easy to use, high efficiency, and operation quality can satisfy agriculture requirement, have characteristics such as " saving of labor saves time, and are inexpensive, practicality; efficient ", can alleviate the resource and environment pressure that brings because of crop straw burning, recover soil fertility.
The Chen Jian pine was delivered " the paddy-field grass-burying rotovator improves and inquires into " on " modern agriculture equipment " magazine in 2004, paddy-field grass-burying rotovator in this article is on the basis that is matched in rotovator on workers and peasants-12K hand tractor, change its main working parts into special-purpose paddy-field grass-burying roll and form, form by main shaft, flange, tulwar, horizontal cutter, upright cutter and the whole seam of shelves grass card.There is following deficiency in this paddy field rotary tillage machine for covering grass:
1. structure more complicated.
2. grass-wrapping problem is comparatively outstanding, twines grass burying between careless roll two ends and hood housing space easily to form, if the words of untimely cleaning, grass can twine more and more, tight more, increase tillage resistance, cause operating efficiency to descend, oil consumption increases, and this phenomenon is particularly serious when the piece operation of high-stubble field.Design is to be used for the retaining grass in the retaining grass card original meaning of burying careless roll two ends, prevent to twine grass, but in fact this retaining grass card does not have due effect.
3. tilling depth instability.
4. vegetation coverage is low.
Summary of the invention
The present invention be intended to invent a kind of simple in structure, low in energy consumption, take off the inclined rotary tillage paddy field straw burying machine that careless performance is good, vegetation coverage is high.
Realize the technical scheme of above-mentioned purpose:
Its by rotary blade of arranging in order in the same way roll, side gear, idler gear transmission case, universal joint, trifilar suspension support and tractor motive power output shaft form.Tractor motive power output shaft is connected by spline with universal joint, and universal joint is connected by spline with intermediate gear box, and intermediate gear box is connected with the side gear by flat key, and the side gear rolls with rotary blade by flat key and is connected.Wherein Oblique Rotary Tillage Blade is rolled and is become 15 °-28 ° of oblique angles with the tractor wheel shaft, and the side cutting blade unanimity of blade is towards the right of direction of advance, two rotary blades of each cutterhead, and phase difference is 180 °.With rotary blade corresponding on the adjacent cutterhead phase difference B is arranged, the size of B is determined by following principle between 30 ° of-120 ° of degree: rotary blade can be removed the constraint of side soil mutually, soil is destroyed in draws.
The present invention rolls, rationally arranges blade by Oblique Rotary Tillage Blade, soil is destroyed in because of tearing draws, and reduces power consumption; The blade movement track is the space trochoidal curve, and its stirring action is stronger, compares with just putting rotary tillage, helps mixing of stalk and soil more, buries carelessness thereby improve.The inclined rotary tillage slip cutting angle better takes off careless performance greater than just changeing rotary tillage so have, and is more suitable for paddy field work.By the universal joint at tractor motive power output shaft place, Oblique Rotary Tillage Blade is rolled and the tractor wheel shaft, and power passes to cutter by intermediate gear box and side uni-drive gear box and rolls.
The operation principle of inclined rotary tillage paddy field straw burying machine is: Oblique Rotary Tillage Blade is rolled, and rotary blade is rolled with direction of advance an angle, by reasonable arrangement blade, makes adjacent rotary blade can remove the constraint of side soil mutually, greatly reduces cutting resistance; Because the lateral movement of rotary blade, make soil because tear and be destroyed in and draw, and the tensile strength minimum of soil, the soil pull and stretch destroys the power minimum that consumes, so the inclined rotary tillage very little light simple rotary tillage mode that is a kind of power consumption.And because the blade movement track is the space trochoidal curve, its stirring action is stronger, compares with just putting rotary tillage, help mixing of stalk and soil more, thereby carelessness is buried in raising.The inclined rotary tillage slip cutting angle better takes off careless performance greater than just changeing rotary tillage so have, and is more suitable for paddy field work.
