Description

Rice seedling box of rice transplanter with enlarged width of bottom plate

Technical Field

The invention relates to the technical field of transplanter structural design, in particular to a transplanter seedling box with an enlarged bottom plate width.

Background

The existing rice transplanting machines all have the problem that the width of the bottom plate of the individual rice transplanting machine is too narrow, and is smaller than the row spacing of 20mm, particularly, the width of the individual rice transplanting machine produced by the narrow-row spacing rice transplanting machine and the wide-narrow row type rice transplanting machine is too small, so that the number of the rice transplanting trays is increased, materials are wasted, the tray loading speed of rice seedling raising and rice transplanting is reduced, manpower is wasted, the probability of empty side seedling taking is increased in the rice transplanting process, and the production is not facilitated.

Disclosure of Invention

The invention aims to solve the technical problem that in order to overcome the defects of the existing seedling box, in order to increase the width of the bottom plate of the individual seedling box, the width of the middle partition plate of the box body is reduced, and the strength of the partition plate is increased, so that the original bottom plate can be widened to the maximum extent by less than 15mm, and particularly, a seedling raising tray of one specification and even a seedling tray of one specification can be commonly used when the row spacing of a seedling planting machine in a large eight-inch row spacing interval is changed, thereby being convenient and improving the efficiency.

The technical scheme is implemented by firstly explaining a large eight-inch row spacing cultivation method for rice, and is specifically characterized in that the yield of the rice is mainly determined by three factors, the number of spikes per unit area, the number of single spikes and the thousand-grain weight are determined, and a land block with medium and low fertility is subjected to fine adjustment of the row spacing by utilizing the characteristic of accurate seedling transplanting of a rice transplanter, a corresponding row spacing is selected between large eight-inch rows (270 mm-290 mm), a plant spacing of 3 inches is used at the same time, the disadvantage that 9 x 3 seedling transplanting is increased by using excessive fertilizer is avoided, the basic number of seedlings is increased to improve the yield, so that the number of spikes per unit area is increased, for a land block with high fertility, a corresponding row spacing is selected between large eight-inch rows (270 mm-290 mm), and a plant spacing of 4 inches is used at the same time, the harm caused by 9 x 3 is avoided, an individual space is properly increased to increase the number of tillers, the number of spikes and the thousand-grain weight, the height and the density of the plant type are reduced, and the yield is stably increased.

Because the large eight-row cultivation method is realized by machinery, in order to adjust the row spacing and increase the width of the bottom plate of the individual seedling box (namely increase the width of a seedling raising tray or a seedling tray), the invention adopts the method that the width of the middle partition plate of the seedling box is reduced, the reduction range is within 15mm, so that the width of the bottom plate of the individual seedling box is increased, the seedling box is basically formed by combining a plurality of independent individual seedling boxes when viewed from the front of the seedling box, the individual seedling box is formed by a bottom plate, the partition plate, a seedling brush and a seedling pressing rod fixer which are fixed at the lower part of the partition plate, and a seedling pressing rod and a seedling blocking rod which are arranged on the seedling pressing rod fixer, the seedling blocking rod is positioned below the seedling pressing rod, and plays the roles of blocking short seedlings and dispersing seedlings, the partition boards positioned at two sides of the integral seedling box are called side partition boards, the middle partition board becomes narrow and weak in strength, when the size is reduced by only 5mm, only the iron plate needs to be thickened and the strength is increased, when the reduction range is larger than 5mm, if the use requirement of the middle partition board cannot be met, the strength of the iron plate needs to be increased, the longitudinal strength and the transverse strength of the middle partition board also need to be enhanced, a whole smooth rib (1) can be longitudinally added close to the top in the groove body of the middle partition board, in order to increase the transverse strength, a transverse rib (2) can be transversely added in the groove body of the middle partition board at intervals of 70 mm-150 mm, the specific shape is as shown in (figure 1), and the seedling brushes are arranged on the side partition boards or the middle partition board and are made into the same width so as to ensure the same abrasion; when the width of the middle partition plate is less than 10mm and more than 5mm, in order to further reinforce the middle partition plate and the seedling brush, the structure (shown in figure 2) of the seedling pressing rod fixer of the middle partition plate is changed, so that the seedling blocking rod (3) and all the seedling pressing rod fixers are fixed after determining the size, the bottom plate of the fixer and the seedling brush are also fixed by screws, the distance of the middle partition plate is fixed by virtue of the side partition plates which are not reduced at the two sides of the box body, the distortion of the middle partition plate and the seedling brush is prevented, and the seedling brush is fixed by using the screws, so that the width of the bottom plate is increased;

has the advantages that: the number of the seedling trays in unit area is reduced, the probability of empty side seedling taking is reduced, materials are saved, the seedling raising and transplanting efficiency is improved, and meanwhile, when the row spacing of the large eight-inch row spacing seedling transplanting machine is changed in the interval, the seedling raising trays of the same specification and even the seedling trays of the same specification can be used by changing the width of the middle partition plate; the existing 9-inch flexible seedling planting disk can be used for the large eight-inch rice transplanter with the row spacing of 290mm,285mm and even 280mm, thereby being convenient for the operation of different models and reducing the waste.

Detailed Description

In order to enable the seedling raising trays or seedling trays with the same specification to be used when the row spacing in the large eight-inch row spacing interval is changed within 270-290 mm, the seedling boxes are respectively made into 8mm, 12mm, 17mm and 22mm corresponding to the partition boards and the seedling brushes according to the figures 1 and 2, the widths of the box bottom plates in the large eight-inch section are 262mm except for the 270mm row spacing, the widths of the box bottom plates in the other four sections are 268mm, the seedling trays with the same specification can be used, the 270mm row spacing is 6mm less than the width of the bottom plate, the same seedling raising tray is required to be used, the seedling raising tray is required to be used by heightening the two sides of the vertical edge by 3mm, the seedling tray larger than 6mm is required to be used, the seedling tray is put into a pool for more than half a day, then the hard tray is put down, the seedling raising tray is used by using the soft tray with the gravity, the 262mm is avoided, the waste of the seedling raising tray with the change of the row spacing in the large eight-290 mm is avoided, and the seedling boxes with the waste of the seedling boxes also comprising 290 mm.
