Description
Technical Field
The utility model belongs to the field of agricultural machinery, specifically speaking, it relates to an adjusting device that is used for paddy field fertilizer distributor depth of fertilization, can independently accurate every fertilization furrow opener depth of fertilization.
Background
The paddy rice is widely planted in China, so the paddy field fertilization is related to the growth quality of the paddy rice, the paddy field fertilization is generally divided into a front period, a middle period and a rear period according to the growth process of the paddy rice, the front period refers to the period from transplanting to tillering termination, namely the vegetative growth stage of the paddy rice, and the fertilization aims at promoting effective tillering and striving for multi-spike; the middle stage refers to the stage that the rice grows and enters a reproductive growth stage (a pollen forming stage), and at the moment, the fertilization aims at strengthening the stalks and attacking the big ears, but the fertilization amount cannot be too much; the later period refers to the period from the ear sprouting to the maturity of rice, at the moment, fertilization is mainly characterized by more grains and full grains, and the rice is not fertilized and cannot be greedy and late maturing.
The fertilization method of the rice in the three periods is actually the principle, theory and target of fertilization, and is really determined in practice according to specific conditions, namely the fertilization amount and the fertilization depth are determined according to different soils and different rice varieties, namely the fertilization depth of a paddy field is very important according to local conditions, most of fertilizer is applied to the soil layer with concentrated root system density in reasonable fertilization, and the fertilizer is applied to the part with stronger root system absorption capacity, so that the fertilizer is absorbed by crops. So the research and development of the fertilizing depth adjusting device of the paddy field fertilizing machine is particularly important. At present, the paddy field fertilizing operation is completed by fixedly assembling a paddy field fertilizing operation device on various paddy field operation machines to form a compound operation machine, such as a rice transplanting and fertilizing machine, a paddy field weeding and fertilizing machine, a paddy field rotary tillage and soil preparation and fertilizing machine and the like. During operation, according to the difference of paddy field mud foot degree of depth, often need realize the regulation to fertilizer injection unit height position through changing various composite machines complete machine high position to satisfy the fertilizer injection degree of depth regulation requirement of different mud foot degree of depth, not only the degree of depth regulation is unstable, and the control range is wayward, and the regulation precision is poor, can not realize single fertilizer injection unit's independent regulation moreover, and adaptability is poor. Therefore, the invention is very necessary to provide the independent and accurate-adjustment fertilizing device capable of realizing single fertilizing device.
Disclosure of Invention
The utility model aims at solving the problems existing in the prior art, the design provides a new construction for adjusting device (as in fig. 1) of paddy field fertilizer distributor fertilization degree of depth, connect on fertilization furrow opener (6) motion sliding sleeve (5), direction inner sliding sleeve (3) suit is on motion sliding sleeve (5) outside, direction outer sliding sleeve (2) suit is on direction inner sliding sleeve (3) outside, sliding sleeve (3) lower part assembly mounting (4) will lead inner sliding sleeve (3) and fix the position on motion sliding sleeve (5), sliding sleeve (3) upper end outside assembly connecting piece (1) in the direction. When the guide outer sliding sleeve (2) rotates, the moving sliding sleeve (5) vertically moves under the combined action of the guide outer sliding sleeve (2) and the guide inner sliding sleeve (3). The device can complete independent adjustment of the depth of a single fertilizing device according to the difference of the depth of a paddy field while integrally adjusting the fertilizing depth operation along with the combined operation machine, and achieves the purposes of high adjusting precision, convenience in adjustment and strong adaptability.
The utility model provides an adjusting device for paddy field fertilizer distributor fertilization degree of depth includes the fertilization furrow opener, threaded connection motion sliding sleeve on the fertilization furrow opener, direction inner sliding sleeve suit is outside on the motion sliding sleeve direction inner sliding sleeve on be equipped with the direction slotted hole along the axial direction, have direction helicla flute direction outer sliding sleeve (as figure 2) suit on the direction inner sliding sleeve outside on the inner hole wall, the uide pin is inserted and is joined in marriage in the direction slotted hole on the direction inner sliding sleeve, the uide pin inboard is adorned admittedly on the motion sliding sleeve, and its lateral part is inserted and is joined in marriage in the direction helicla flute on the direction outer sliding sleeve, passes through threaded connection mounting fastening position in direction inner sliding sleeve lower part, passes through threaded connection fit in the direction inner sliding sleeve upper end outside and joins in marriage the connecting piece, the connecting piece cooperates with direction inner sliding sleeve and fixes direction overcoat axial.
The guide outer sliding sleeve is rotated, so that the spiral groove on the inner side of the guide outer sliding sleeve is rotated, the guide spiral groove drives the guide pin to move, and the guide pin is arranged in the guide groove of the vertical guide inner sliding sleeve, so that the movement sliding sleeve on the furrow opener is driven to move along the vertical direction.
The moving sliding sleeve is constrained by the guide inner sliding sleeve and the guide outer sliding sleeve together, so that the degree of freedom of the moving sliding sleeve is 1, the moving sliding sleeve can only do telescopic motion in the vertical direction, and the telescopic value of the moving sliding sleeve is S.
When the moving sliding sleeve is positioned at the topmost end (as shown in the following figure 3), the stretching amount S at the moment is taken as the minimum value Smin ═ 0 (unit mm).
When the moving sliding sleeve is positioned at the lowest end (as shown in the following figure 4), the expansion amount S at the moment is taken as the maximum value Smax which is 130 (unit mm).
And analyzing a position relation equation of the expansion value of the moving sliding sleeve S and the rotation angle of the outer sliding sleeve theta (the rotation angle of the guide outer sliding sleeve is theta).
When S is Smin, the rotation angle theta of the outer sliding sleeve is 0, namely the rotation angle theta is taken as the initial position.
(see FIG. 5 below)
When S equals Smax, the rotation angle of the outer sliding sleeve is θ equals 4 × 360 degrees (known from the above equation of the thread groove trajectory parameter of the outer sliding sleeve), that is, the rotation angle is the final position. (see FIG. 6 below)
When theta is rotated by 1 degree, S is equal to S1，S1＝(130×1)/(4×360)
Obtaining a position relation equation of the expansion value S of the moving sliding sleeve and the rotation angle theta of the outer sliding sleeve: s is 130 θ/(4 × 360).
The utility model has the advantages of reasonable design, simply, can be along with the whole paddy field fertilization degree of depth of each fertilizer injection unit that carries out of paddy field double entry operation machines, can independently fertilize the degree of depth to adjust to each fertilization monomer unit again, its fertilization degree of depth adjustment precision is high, and fertilization adaptation paddy field condition can the reinforce, and application scope is wide, can assemble and use on such as rice transplanter, paddy field weeder, paddy field rotary tillage soil preparation machines, and it is simple and easy convenient to adjust the operation, and the operation is reliable.
