Description
Technical Field
The invention relates to the technical field of crop production equipment, in particular to a broad bean tipper.
Background
Broad beans are the largest edible bean variety planted in my province, and the planting is mainly distributed in the zhongzhong county, the source county, the datong county in xindong city, the mutually-aided county in hai east city, and the tableland area in hainan province. Broad beans are one of important crops for adjusting planting structures and increasing income of farmers in our province. At present, broad bean seedlings are sharpened by manpower, the labor intensity is high, the production cost is high, the labor cost is over 50 percent of the total production cost, the situation that no person is available is generally existed along with the transfer of rural labor force, and the development of the industry is greatly limited. In order to improve the quality of the broad beans, reduce the agricultural production cost and improve the mechanical production level of the broad beans, the optimal mechanism design suitable for broad bean pinching operation is determined.
Broad bean seedlings refer to broad bean seedlings, the broad bean seedlings are usually subjected to sharpening treatment when being planted, the sharpening has the advantages that the growth of young shoots can be temporarily delayed, the nutrition competition among young shoots, spica and fruits is reduced, the concentrated supply of nutrient substances to the spica and the fruits is promoted to grow, the fruit setting rate is favorably improved, the fruit expansion is promoted, the fruit quality is improved, the young shoots are usually subjected to shearing through sharpening equipment when being sharpened, in the actual operation, the young shoots are close to the spica and the fruits, the spica and the fruits are easily cut off due to errors, the fixation and the cutting of the young shoots are not favorably carried out, the removed young shoots are easily stopped on the broad bean seedlings after being cut, the judgment of operators is not favorably realized, and the inconvenience is brought to the continuous work.
Therefore, aiming at the problems, the unit designs a broad bean seedling planting and pointing device, and applies for obtaining Chinese utility model patent (No. CN 213044285U), the pointing device forms an opening for cutting off young sprout of broad bean seedling through the arrangement of a fixed rod and a guide rod, so that the position limitation is convenient during cutting off, when the young sprout which is not easy to fix is cut off, the young sprout can be compressed by pushing a shifting block, the convenience is brought to the operation, and the young sprout is cut off after being fixed; the young sprout after being cut off can be poked through the setting of pappus brush, prevents that the young sprout from falling again to the pea seedling and causing the difficult problem of judging of operating personnel, conveniently carries out continuing going on of young sprout shearing, improves the efficiency of pinching of pea seedling.
In practical use, however, there are still some disadvantages: firstly, although the device realizes the mode of directly pinching and removing broad bean seedling tips by using machinery instead of manual work and the fixation of the seedling tips, because the heights of broad bean seedlings are usually not large, when a tippling person operates the device, the cut-off opening position has a longer distance from human eyes, the diameters of the broad bean seedlings are smaller, and side leaves, flower ears and the like are attached to the periphery of the broad bean seedlings, great inconvenience is brought to the accurate positioning of the broad bean seedlings in the cut-off openings, and the seedling tips are tightly pressed on the two sides of the guide rod by the limiting rod through pushing the shifting block and a series of transmission according to whether the seedling tips are easy to fix or not, so that the labor intensity of the tippling person is increased to a certain extent, and the working efficiency is reduced; secondly, for the pinching of broad bean seedling tips, only 3-5cm of the broad bean seedling tips are required to be removed usually, and a pinching person holds the pinching device for remote operation, so that the cutting height position of the seedling tips is not easy to determine, the cutting length is too large or too small, the yield of the seedling in the later stage is influenced, the cutting opening of the seedling is easily damaged in the cutting process by the holding operation, the wound healing is not facilitated, and the normal growth of the seedling in the later stage is influenced.
